Free 4G filters

at800 to send 28,000 filters to households in west London for next phase of 4G testing

at800 is holding a further test to help understand the extent to which 4G at 800 MHz may disrupt Freeview. Approximately 28,000 households in Brentford and Isleworth will be sent a free at800 filter ahead of the test, which begins on 29 April. at800 is the organisation tasked with ensuring viewers continue to receive Freeview when 4G mobile services at 800 MHz are launched later this year*.
 
The at800 filter is designed to block 4G at 800 MHz. Most people will be able to fit the filter themselves, though support is available for eligible viewers.** Only new 4G services at 800 MHz coming later this year could cause problems with Freeview. Existing 4G from EE operates at 1800 MHz and cannot disrupt television.
 
Simon Beresford-Wylie, chief executive of at800, said, This test will help us assess any problems viewers may have with fitting filters and whether receiving one in advance improves awareness and understanding of the potential issue. We will have professional testing units and aerial installers in the area to help get Freeview services back to normal if they are affected by our test.
 
The at800-branded filter is smaller than a pack of cards. It is a passive device - meaning it does not require a power supply - and simply connects between an existing aerial cable and television, or Freeview box. If viewers have an amplifier or signal booster the filter needs to be connected between the antenna and the amplifier.  
 
If viewers have difficulty fitting the filter, they should visit www.at800.tv or call the at800 contact centre on 0333 31 31 800. For residents in buildings with a communal aerial system - where the antenna or aerial is not their responsibility - at800 will provide the building landlord or property manager with a free communal filter on request.
 
at800 has advised that if youve not been contacted directly through the post any interference to your Freeview service is unlikely to be due to the 4G test.  TVs connected to a cable or satellite service are not affected.
