The UK 700MHz and 800MHz frequency clearance reallocated former television broadcasting bands to high-power 4G and 5G mobile base stations. Strong mobile signals overload older wideband television amplifiers, causing severe pixelation. Fitting an in-line CAI-certified LTE/5G micro-filter completely eliminates signal breakup.

Have you noticed your digital Freeview TV channels suddenly freezing, breaking up into mosaic pixels, squeaking loudly, or displaying a persistent "No Signal" error banner—often coinciding with specific times of the day? If your TV aerial is mechanically sound and was working perfectly until recently, the root cause is almost certainly radio frequency interference from nearby 4G and 5G mobile broadband phone masts. Following Ofcom's national 700MHz and 800MHz digital clearance programmes, high-power mobile network data transmissions operate directly adjacent to terrestrial television broadcast channels. In this technical diagnostic guide, lead aerial engineer Gary Pearce explains how mobile mast transmissions swamp television tuners and reveals the certified filter solutions that restore flawless HD reception.

📡 The 700MHz Clearance Explained
Traditionally, UK television broadcast across UHF channels 21 to 68 (470MHz to 860MHz). In two major spectrum clearance auctions, the UK government sold off the top broadcast frequencies (channels 49–68) to mobile phone networks (EE, Vodafone, Three, and O2) for high-speed 4G and 5G mobile broadband. Today, digital Freeview television is restricted to channels 21 to 48 (470MHz to 694MHz). When a nearby mobile mast transmits high-power 5G data at 700MHz, it overloads older wideband TV aerials and distribution amplifiers with powerful radio noise.
1. Common Symptoms of 4G and 5G Mobile Interference
Mobile interference presents distinctive symptoms that differ from normal weather-related signal fade:
Peak-Time Pixelation: TV reception is perfect at 11:00 AM, but between 5:30 PM and 9:00 PM (when local mobile phone usage surges), channels 40 to 48 begin stuttering and dropping out.
Complete Loss of Specific Multiplexes: Channels broadcast on higher UHF frequencies (often HD channels like BBC One HD, ITV1 HD, or Channel 4 HD) disappear entirely while standard-definition channels remain watchable.
Amplifier Overload (Clipping): If you have an active masthead booster or multi-room amplifier in the loft, the high-power mobile signal overdrives the internal amplifier transistors, creating harmonic distortion across every television in the house.
2. The Solution: High-Rejection Group T (Ch 21–48) LTE Filters
Spectrum Allocation
2026 Engineering Blueprint
UHF Spectrum Clearance: Freeview TV (470–694MHz) vs Mobile 4G/5G Bands
Freeview TV (Channels 21 to 48)
Broadcast frequencies: 470MHz to 694MHz. Passes through high-rejection LTE filter with under 1.5dB insertion loss for crystal-clear HD viewing.
Mobile 4G/5G (700MHz & 800MHz)
Broadcast frequencies: Above 694MHz. Attenuated by over 50dB by the filter, preventing cellular tower transmissions from overloading TV tuners.
Eliminating mobile interference requires installing a CAI-benchmarked 700MHz/800MHz LTE Low-Pass Filter:
Steep Frequency Cutoff: The filter allows frequencies between 470MHz and 694MHz (TV channels 21 to 48) to pass with less than 1.5dB of insertion loss, while providing over 50dB of active rejection against frequencies above 694MHz. Mobile signals are attenuated by 99.999% before they reach your TV tuner.
Correct Placement: The filter must be installed before any amplifier in the signal chain. If placed after an overloaded amplifier, it cannot remove the harmonic distortion already created.

The 700MHz Clearance & Telemetry Filtering Guide
BLUF Direct Answer: Mobile network operators use the 700MHz and 800MHz frequency bands for 4G and 5G cellular data, which directly borders Freeview UHF TV channels 21 to 48, causing severe Freeview picture pixelation, sound popping, and missing multiplex channels unless a certified 700MHz low-pass filter is installed.
Following Ofcom's 700MHz clearance programme, UK television broadcasting was compressed into channels 21 to 48 (470MHz to 694MHz). High-powered 4G and 5G mobile phone masts broadcasting at 700MHz (channels 49 to 60) transmit signals up to 40dB stronger than terrestrial TV broadcasts.
This overwhelming cellular energy overloads older unshielded aerial amplifiers and TV tuners, creating intermodulation distortion that manifests as broken, pixelated video or total 'No Signal' errors. Fitting an inline CAI-certified 700MHz/800MHz LTE filter or upgrading to a shielded group-T aerial rejects all cellular noise with over 45dB of out-of-band attenuation.

How to Diagnose and Filter 4G/5G Mobile TV Interference
Troubleshooting and filter installation steps for pixelating Freeview TV.
1
Identify Symptom Patterns
Notice if TV channels randomly pixelate or glitch when smart phones in the room download data or when near a cell tower.
2
Locate Existing Signal Amplifier
Find any aerial distribution amplifier in the loft or behind TV points; check if it has a 4G/5G filter label.
3
Install Inline 700MHz Low-Pass Filter
Fit a screened F-type 700MHz filter directly between the aerial downlead cable and the amplifier input.
4
Retune Freeview Channels
Perform a fresh automatic channel retune to lock into the clean 470MHz-694MHz broadcast multiplexes.
3. Double-Screened Cable: Why WF100 Coax is Mandatory
Even with a filter installed, poor-quality coaxial cable can act as an antenna, picking up 5G mobile signals directly through the cable jacket:
Older brown low-loss coaxial cable has a loose, single copper braid with less than 60% optical coverage. Mobile signals radiate straight through the gaps. Our engineers strictly install Webro WF100 double-screened cable, featuring continuous copper tape foil plus a dense 100% copper braid, providing certified 100dB screening immunity against cellular ingress.

Gary Pearce Field Commentary:
"If your Freeview TV starts pixelating at half past five in the evening when everyone in the street gets on their mobile phones, you have 4G or 5G interference. Installing a calibrated 700MHz low-pass filter right before your amplifier blocks the mobile signal by fifty decibels, restoring your TV instantly."

Why did my Freeview TV suddenly start pixelating after working fine for years?
In many areas, mobile network operators (EE, Vodafone, O2, Three) have recently activated new 4G or 5G base stations on the 700MHz or 800MHz frequency bands. Because these frequencies were previously used for television, older aerial systems pick up the powerful mobile phone signals, overloading your TV tuner.
What is an LTE filter and where is it installed?
An LTE filter is a low-pass electronic filter that allows television broadcast frequencies (470–694 MHz) to pass through untouched, while sharply blocking signals above 700MHz. It is installed in-line on the coaxial cable between your aerial and your TV or amplifier.
Can a G/G filter fix a weak TV signal?
No. An LTE filter only stops mobile phone mast overload. If your aerial is misaligned, damaged by storms, or has waterlogged cables, a filter will not restore missing channels; the aerial itself must be repaired.
How can I tell if my TV problem is mobile interference or a broken aerial?
Mobile interference often causes pixelation and sound screeching on specific groups of channels (multiplexes) while other channels remain perfect. Weather damage usually affects all channels equally or causes a permanent 'No Signal' message.
Do smart G phones inside my house interfere with my TV?
If you use cheap, unshielded coaxial flyleads between your wall socket and television, a 5G phone transmitting nearby can leak RF energy into the unshielded wire, causing temporary picture breakup. Replacing flyleads with double-screened metal-bodied leads eliminates this.

Complete Physical Engineering & Diagnostic Guide: Why 4G & 5G Mobile Masts Break Up Freeview TV Pictures (LTE Filter
Across Yorkshire, Lancashire, Greater Manchester, Cheshire, Humberside, Nottinghamshire, and Teesside, homeowners and commercial facility managers rely on ADI Communications for physical low-voltage engineering that performs reliably for 10 to 15+ years. Whether you are researching Why 4G & 5G Mobile Masts Break Up Freeview TV Pictures (LTE Filter, planning a domestic security or connectivity upgrade, or diagnosing an intermittent signal or network fault, understanding the physical layer—cabling conductors, optical physics, radio-frequency attenuation, and structural wall fixings—is essential to avoiding costly mistakes.
Unlike national call-centre franchises and lead-generation directories that subcontract work to unvetted handymen using cheap Copper-Clad Aluminium (CCA) wire and indoor-grade plastic plugs, Lead Engineer Gary Pearce carries out every site survey, physical installation, and calibrated meter test personally. With over 25 years of hands-on trade experience since 1999 and formal NVQ qualifications across Aerials & Satellite (Level 1–3), Data Cabling & Fibre (Level 1–4), Electrical (Level 1–3), and CCTV Security Systems, our engineering protocols are built around British Standards (BS EN 62676-4, BS 5839-6, BS 7671, and EN 50131 Grade 2).
01 • Pure Copper Infrastructure
100% Solid Bare Copper Cabling (Zero CCA)
Every metre of external and internal cable we install—whether Cat6/Cat6A Ethernet for PoE security cameras and Wi-Fi 6 access points, or CAI-benchmarked WF100 twin-screened foam-dielectric coaxial cable for Freeview HD and satellite feeds—uses 100% solid 23AWG/24AWG oxygen-free bare copper. Solid copper prevents IEEE 802.3af/at PoE voltage drop over long runs, eliminates high-frequency RF skin-effect attenuation, and resists brittle snapping or galvanic corrosion inside damp exterior junction boxes.
02 • Structural Substrate Anchoring
Engineered Fixings for Stone, Brick & Drywall
Northern and Midland properties span Victorian millstone grit, Yorkshire sandstone, Accrington engineering brick, lime-mortar cobbles, and modern dot-and-dab insulated plasterboard. We match every bracket to the exact wall substrate: heavy-duty hot-dip galvanised Pennine storm brackets and twin stainless-steel chimney lashing cradles for rooftop Starlink and aerial masts; steel-cored CoreFix 100 dot-and-dab bridge anchors and M6 SnapToggle hollow-wall toggles (rated to 120kg) for large-screen OLED/QLED TV wall mounting.
03 • Calibrated Meter Verification
Fluke Networks & Spectrum Analyser Testing
Guesswork has no place in professional telecommunications. Before any job is signed off, we verify physical-layer performance using calibrated instruments: Fluke Networks cable verifiers for Cat6/Cat6A wiremap continuity, pair skew, and PoE load voltage under night-time LED surge; digital RF spectrum analysers measuring Modulation Error Ratio (MER ≥ 32dB) and pre-Viterbi Bit Error Ratio (BER) across UHF Freeview multiplexes; and SpaceX Starlink 110° phased-array sky-obstruction telemetry.
4K ColorVu & TiOC Surveillance
F1.0 super-aperture 24/7 full-colour night vision turrets fitted with IP66 weather-sealed aluminum junction bases and pure copper Cat6 PoE cabling.

Domestic Home Priority vs Commercial & Industrial Specification
Over 70% of our day-to-day work across Yorkshire and the North West involves domestic residential homes—terraced properties, semi-detached family houses, detached executive homes, rural farmhouses, and residential apartments. In a domestic setting, homeowners care deeply about two things: rock-solid reliability and spotless aesthetics. Nobody wants ugly white cables draped over roof tiles, trailing across bay windows, or tacked loosely along internal skirting boards. When Gary Pearce installs a 4K CCTV system, SpaceX Starlink dish, Cat6 Ethernet point, or wall-mounted television in your home, exterior cables are matched to your brickwork or render (black, white, or brown UV-stabilised PE sheath), tucked behind rainwater downpipes, and drilled on an upward internal incline with a weather-shedding drip loop and high-modulus silicone seal.
We also provide full installation and troubleshooting support for customer-supplied equipment. Many homeowners purchase a Hikvision, HiLook, Swann, Reolink, Annke, TP-Link Tapo, EZVIZ, Ring, or Eufy kit online or from a retail store, only to discover that working safely at roof height, drilling through 18-inch stone walls, crimping 8-pin RJ45 connectors, or configuring router port-forwarding and NVR storage requires specialist trade tools. Whether you want us to supply and fit a complete trade-grade system or professionally install hardware you have already bought, you receive the exact same calibrated testing and workmanship care.
For commercial clients—including retail shops, hotels, B&Bs, pubs, restaurants, car parks, apartment blocks, student HMOs, warehouses, farms, caravan parks, and construction sites—we scale up to industrial specifications. Commercial deployments incorporate NDAA-compliant Uniview, Dahua WizMind, and Hikvision AcuSense/DarkFighter hardware, 25x–42x optical zoom auto-tracking PTZ domes, dedicated ANPR number-plate recognition lanes, dSCR communal IRS satellite multiswitches, EN 54 / BS 5839-6 Grade D1 interlinked wireless fire detection, and rack-mounted 19-inch Cat6A patch panels—all backed by £10 Million Public Liability Insurance and full RAMS documentation.

Frequently Asked Questions: Why 4G & 5G Mobile Masts Break Up Freeview TV Pictures (LTE Filter
Who carries out the installation and diagnostic work at ADI Communications?+
Every survey, installation, and fault-finding visit is carried out directly by company founder and Lead Engineer Gary Pearce. We never sub-contract jobs to third-party agency labourers. Gary holds over 25 years of hands-on experience and formal NVQ qualifications across aerials, satellite, structured data cabling, fibre optics, electrical installations, and CCTV security systems.
Can you install CCTV cameras, Starlink dishes, or smart doorbells that I have already bought myself?+
Yes. Alongside supplying and fitting our own trade-grade Hikvision ColorVu, Dahua TiOC, Uniview, and Ajax packages, we offer a dedicated customer-supplied hardware installation service. We mount your units using trade-grade stainless steel or galvanised fixings, replace flimsy factory patch leads with 100% solid copper exterior cabling, weatherproof all masonry entry points, and configure your mobile apps.
Why do you insist on 100% solid bare copper Cat6 and WF100 coaxial cable instead of cheaper CCA wire?+
Copper-Clad Aluminium (CCA) cable has roughly 55% higher DC electrical resistance than pure bare copper. Over runs exceeding 20 metres, CCA causes severe Power over Ethernet (PoE) voltage drop—making 4K CCTV cameras reboot at night when their ColorVu or infrared LEDs switch on—and suffers rapid oxidation inside damp outdoor junction boxes. Solid bare copper guarantees full IEEE 802.3af/at PoE delivery, 10Gbps bandwidth headroom, and a 15-year+ outdoor service life.
Are there any mandatory monthly subscription fees for your CCTV or Ajax alarm systems?+
No. You own all installed hardware outright from day one with £0 mandatory monthly fees to ADI Communications. Our 4K PoE CCTV systems record 24/7 onto a local Western Digital Purple surveillance hard drive inside your NVR, and both Hik-Connect/DMSS and the Ajax Security System smartphone apps send instant push alerts and live HD video to your phone completely free of charge.
Which UK regions and postcode districts does ADI Communications cover?+
We operate equipped mobile workshop vans across West, South, North, and East Yorkshire (Leeds, Bradford, Wakefield, Sheffield, Huddersfield, Halifax, York, Harrogate, Doncaster, Hull), Lancashire and Greater Manchester (Manchester, Preston, Blackburn, Burnley, Bolton, Wigan, Oldham, Rochdale, Stockport), Cheshire (Warrington, Chester, Crewe, Macclesfield), Humberside and Lincolnshire (Grimsby, Scunthorpe, Cleethorpes), Nottinghamshire, and Teesside/County Durham.
How do you mount heavy TVs safely onto modern dot-and-dab or hollow plasterboard walls?+
On dot-and-dab walls—where 12.5mm plasterboard sits over a 15mm–25mm air gap in front of thermal blockwork—we drill 100mm deep into the structural blockwork and insert steel-cored CoreFix 100 anchors so the steel sleeve bridges the void without crushing the plasterboard. On timber or metal stud walls, we anchor into the studs and deploy heavy-duty M6 SnapToggle steel wing anchors rated up to 120kg.
How do you protect slate and rosemary tile roofs when installing SpaceX Starlink or TV aerials?+
We never bolt brackets through roof slates or clay tiles. On homes with a sound chimney stack, we fit a non-drill stainless steel chimney lashing cradle using twin 5mm steel tension wires wrapped around the stack—distributing wind loads across four courses of brickwork without drilling a single hole into the mortar. On properties without chimneys, we mount heavy-duty hot-dip galvanised stand-off brackets into the solid gable-end masonry below the bargeboard.
What is the best way to get fast Wi-Fi into a garden office, summerhouse, or outbuilding?+
Plug-in powerline adapters fail across separate RCD consumer unit circuits, and domestic mesh nodes cannot push 5GHz signals through double glazing and foil-backed outbuilding insulation. We engineer two permanent solutions: either a direct-burial Steel Wire Armoured (SWA) Cat6A copper cable feeding an internal PoE Wi-Fi 6 access point, or a matched pair of external 5GHz/60GHz point-to-point wireless bridge dishes when a patio or driveway prevents trenching.
Are your commercial and HMO installations fully insured and compliant with UK regulations?+
Yes. ADI Communications carries £10,000,000 Public Liability Insurance, provides full Risk Assessments and Method Statements (RAMS) for commercial sites, and issues formal commissioning certificates and VAT invoices across BS EN 62676-4 (CCTV), BS 5839-6 Grade D1 / EN 54 (wireless fire detection), and BS EN 50131 Grade 2 (intruder alarms).
What warranty do you provide on your installations and repairs?+
Every installation and structural mounting bracket fitted by Gary Pearce is backed by our comprehensive 1-to-3 Year Workmanship and Hardware Guarantee. If any bracket, cable termination, or supplied component experiences a fault under normal operating conditions, we return and rectify it promptly with zero call-out charge.
Regional Field Engineering Standards Across Yorkshire, Lancashire & the North
Every property across Northern England and the Midlands presents distinct environmental, structural, and radio-frequency conditions. On high-altitude Pennine properties across Saddleworth, Holmfirth, Hebden Bridge, Todmorden, Skipton, Ilkley, and Harrogate, rooftop SpaceX Starlink Gen 3 dishes and digital Freeview HD aerials face winter wind gusts exceeding 80 to 90mph alongside driving sleet and horizontal rain. Standard lightweight alloy brackets or single-band chimney straps twist out of alignment during the first autumn gale. That is why our rooftop installations use heavy-gauge 2-inch steel masts, twin 18-inch stainless steel chimney lashing cradles tensioned with 5mm galvanised wire, and hot-dip galvanised stand-off wall brackets anchored into solid mortar courses with M10 bolts.
Inside heritage Victorian and Edwardian stone terraces, converted mills, and rural farmhouses across Leeds, Bradford, Wakefield, Sheffield, Huddersfield, York, Manchester, Bolton, Blackburn, and Preston, 18-inch solid stone internal walls and foil-backed Celotex cavity insulation block 5GHz and 6GHz wireless signals completely. Relying on wireless-only plug-in Wi-Fi boosters or battery-powered security cameras in these properties leads to constant dropouts and missed motion events. By routing discrete, UV-stabilised external or internal 100% solid bare copper Cat6 and Cat6A Ethernet links from your primary router to hardwired ceiling access points (Ubiquiti UniFi, TP-Link Omada, Deco, or eero Pro) and PoE security cameras, we deliver full Gigabit speeds and unshakeable 24/7 recording into every room and outbuilding.
On modern new-build housing estates across Doncaster, Rotherham, Barnsley, Pontefract, Castleford, Warrington, Stockport, Hull, Scunthorpe, Grimsby, Mansfield, and Teesside, internal walls are almost universally constructed from 12.5mm dot-and-dab plasterboard bonded over thermalite breeze blocks or lightweight metal studwork. Hanging a 65-inch, 75-inch, or 85-inch OLED, QLED, or Sky Glass television on standard plastic rawlplugs risks pulling the plasterboard away from the wall. Our TV wall mounting service uses steel-cored CoreFix 100 dot-and-dab anchors that bridge the cavity air gap directly into the load-bearing blockwork, paired with M6 SnapToggle hollow-wall toggles rated to 120kg and concealed in-wall brush plates so not a single HDMI or power lead is visible.
Whether you are booking a domestic home upgrade, an installation of customer-supplied CCTV or Starlink hardware, an emergency coaxial or Cat6 cable splice repair, an independent Openreach NTE5C master socket relocation, or a multi-camera commercial and HMO compliance project, you deal directly with Lead Engineer Gary Pearce from your initial telephone enquiry right through to final calibrated testing and handover.
