What To Do If Your Freeview Is Disrupted By 4G

This is a sponsored post on behalf of at800.

As 4G masts are switched on for London, those living nearby may experience disruption to their Freeview TV service.

Current 4G services run by the EE mobile network operate at 1800MHz, which does not affect Freeview. One of the upcoming frequencies, 800MHz, was a frequency previously used by Freeview. As a result, some people’s television equipment may still pick up this signal, potentially causing disruption to their existing Freeview service. You may experience loss of sound, blocky images or lose some channels. Your television picture may be disrupted or give you a 'no signal' message.

Only around 90,000 homes across the country are expected to be affected by 4G at 800MHz and if you are in a potential problem area, at800 will send you a postcard warning at least three weeks before the local mast switch on. If you subsequently experience any disruption to your Freeview TV service, at800 are here to help you.

You may be sent a special plug-in filter to correct the issue. If that doesn't do the job, at800 will look at your specific circumstances and work out a way to get your primary telly back to normal so you can continue watching the free-to-air TV channels you are entitled to receive under the TV licence fee.

Remember, only people who watch TV on Freeview are at risk of disruption. Satellite and Cable services will not be affected.

This is basically another millennium bug story. There is no threat to freeview services


@dav True, but having stockpiled hundreds of thousands of worthless filters, they need to be able to get rid of them some way.


dav - not strictly true about the millennium bug. There were issues which would have affected some apps and systems but most of these were sorted in time. I can understand why people thought it was a case of scary headlines and then nothing happened but that's because all the work of the previous 5 or 6 years paid off. Oh - and there is a slight risk to Freeview services but no so much in London as the frequency band used by the Crystal Palace transmitter is not adjacent to the 800MHz 4G band (Crystal Palace uses 490-546MHz for it's frequencies). Those in area's served by the higher channel numbers (above channel 50) may not be so lucky.


Received the AT800 postcard; phoned the AT800 helpline because the picture had started pixcelating intermittently since the introduction of 4g. They ran through some basic diagnostic questions on the phone but refused to send a filter. I then resolved the problem myself by ordering one of the AT800-approved filters from Amazon for less than £10. Disappointed that AT800 helpline wasn't more helpful.
