It's all about the new 4G mobile services that may be coming to your area soon. They operate at 800 MHz, a similar frequency to Freeview,and so may cause problems like loss of TV channels, blocky images and loss of sound.
Has anybody on the forum [who watches Freeview] been affected yet?
Thanks for the responses. I get my TV aerial signal from a large communal roof aerial [40 flats sharing] but I am more worried that the FM radio signal [it comes from same roof aerial] which may also get disrupted, as I listen to and record many Radio4 programs [the signal is very good at the moment but this may not be the case when the 4G masts are switched on in my part of the country ... central Scotland].
