The same situation existed around Bath. Even in the late 1970's there were quite a few pockets that were out of reach of either the Mendip or the local Bathampton UHF transmissions where our customers had to stick with the VHF 405 service either from the local Bathampton relay with BBC1 on ch6 and ITV on ch8 or from Wenvoe/St Hilary with BBC1 on ch5 and ITV on ch10. It was fun keeping the last generation dual standard tv's such as the BRC 1400'S and RBM A640'S going for so long.
Despite these areas having quite a weak 405 signal they could use quite modest VHF TV aerials to get acceptable reception
