In Cwmbran, South Wales. Used to have good reception across all channels. Now some breaking up and everything at 770MHz is unwatchable. Is this 4g interference? Have tried retuning often.

TT: This would seem doubtful, although you can always check with at800:
Contact at800 / DMSL | General Enquiries | at800
Looking at the coverage checkers of O2, Vodafone and Three, they provide no 4G service in Cwmbran. EE does, however it was allowed to use some of its 1,800MHz allocation (which is used for 2G) so we don't know whether it is at 800MHz which is that which can cause issues with TV reception.

Peter: Why would that be? BBC FOUR has never shown a Wimbledon match (as it's not usually transmitting), and it's not really CBeebies target audience either...?

Briantist: Presumably the red button HD stream(s) will return. "But at the point of our launch it covers 50% of UK homes, including the main city in each nation, and it will extend to cover 70% of UK homes by Wimbledon 2014."

The Frome transmitter provides HD on Channel 28 at a power of just 2 Watts, so is likely to be a very local coverage service only, it being siituated close to North Parade and Willow Vale. Mendip provides HD on Channel 59 at 100 KiloWatts and is available over a much wider area.
Depending on the geography between you and Mendip you may be able to get full services from there unless you are 'hidden' from Mendip by the hill in the direction of Mendip at about 2km out from your location.
Trowbridge is widely served by Mendip and has few geographical problems.
Note that Mendip used Group C/D vertically polarised whereas Frome uses Group A aerials vertically polarised. So by looking at your aerial your should be able to tell which it is pointing at, if the cross rods are upright it is on Frome, if there are across then it is Mendip.

@ MikeP - Mendip is horizontally polarized, which from the context of your writing I think you meant to write. Paul, horizontally aligned aerials have their elements parallel to the ground.

Well spotted, a spot of finger trouble!
I did state that Mendip aerials have the rods horizontal.
