In-line 4G Filter c/w Coax Tv Connections
Why filters are needed and why SLX/Labgear filters are ideal for the job
Fact: The UK Digital Switchover was planned to clear frequencies for future technologies between Ch63 68.
But in 2008 the standard for 4th Generation Long Term Evolution (4G LTE800) devices was agreed which used Ch61 and 62.
This has created a very tight space for these new technologies and a higher risk of interference.
Fact: Ofcom estimate that almost 10% of homes (2.4Million) will be affected by interference to their DTT reception
because they are close to a mobile mast carrying 4G and are either:
Receiving DTT on Ch59 or 60 and getting adjacent channel interference (approx 37%)
or they have a UHF amplifier (or 5-wire multi-switch) in their TV system (approx 63%)
Fact: To prevent interference from 4G LTE800 transmitters:
You need a filter with a sharp cross-over from the pass-band to the stop-band
You need a filter with VERY high rejection across the whole 4G LTE800 frequency range
SLX/Labgear 4G filters have been specifically designed to meet the above requirements.
They pass signals in the 462-782MHz range and reject signals across 791-862MHz range with an average rejection level of -55dB.
