Industry & Trade
Both 4G mobile services and digital terrestrial TV (DTT) use parts of the radio spectrum – bands of frequencies – to reach us. The 800 MHz frequencies used by some 4G services are next to the frequencies used for Freeview. There is a very small chance that TVs, recorders and set-top boxes that receive Freeview may have the service blocked by these 4G signals, causing interference.
Most 4G interference problems can be solved by fitting a filter between the TV and the aerial. A range of filters are available for different indoor, outdoor and communal situations, with versions for each to resolve interference on UHF channels up to channel 59 or for cases where TV services reside on UHF channel 60.
4G filter types
A range of filters is available for different situations including indoor, outdoor and communal environments and with different models to resolve interference on channel 59 and channel 60.
All our outdoor and communal filters are designed and tested for outdoor use where adverse weather conditions can occur.
DTG Testing was awarded the contract to test filters that are used to protect digital terrestrial television from interference caused by 4G mobile broadband signals at 800 MHz.
