There was a similar scare when C5 started terrestrial broadcast
umpty-zillion years ago.
And of course, if the issue is interference on Terrestrial TV, then it's
hardly going to be an additional cost for "cable television" as that
The problem seems to be that 4G will use the spectrum that used to be
Channels 61 upwards, immediately above post-switchover DTT. If your
receiver is particularly crap, and you have a wideband or Group CDE
aerial for the higher bands, and it's pointed at a nearby 4G base
station, then an extra low-pass filter might be needed. But TV aerials
can be quite impressive low-pass filters all on their own!
Look at these Group A aerials (in red) for example: http://www.aerialsandtv.com/_wp_gene...wp72596a28.jpg
Or these Group K ones (in grey): http://www.aerialsandtv.com/_wp_gene...wp380af5c4.jpg
