We've just been staying in a holiday cottage west of Bristol. The TV
reception was poor - no signal from Mendip due to a hill being in the
way, so reception was from Wenvoe (about 30km west).
According to https://ukfree.tv/transmitters/tv/Wenvoe
have been good, but it wasn't. There was nothing on Com 6, 7, and 8 -
none of the 3 TVs there would even register their existence. PSB1/BBCA
was very weak most of the time, with extreme pixellation and
intermittent sound (is there a technical term for those loud squeaks?).
Often there was no picture or sound on any of that Com's channels. There
were no radio stations available. PSB2 was similarly weak. Basically,
those Com's SD channels were essentially unviewable.
PSB3 was fine, with the HD channels for BBC1, 2, ITV1, Ch4 and Ch5
showing no breakup at all.
Com 5 was also OK, with no breakup at all, despite being at half the
power (50kW) of the other Coms. And, most annoying, local channel "Made
in Cardiff" came through loud and clear, even though only transmitting
The aerial was a 5-bay (7-element in old money) x-beam feeding an SLX
6-output amp. In my opinion the aerial was misaligned, pointing up about
20 degrees, and south of the correct line to Wenvoe (the cottage next
door had perfect reception on SD with its 9-element x-beam).
Any comments on the poor SD reception?
