In reply to MM6ADR:
Well there’s analog TV on ch.67 (842MHz), DAB on 220 MHz and BandII FM radio on 100ish MHz. Those things are not usually the problem. Although my old contesting group used to have a 70cms preamp that didn’t like the Band II FM on Cyrn-y-brain and needed a stub tuned to a Radio3 (or a harmonic) on its input. The problem is usually caused by all the PMR crud and cruft which grows on the masts. Nice to know you had no problems on VHF at least.
Microwave dishes is the correct term. What you don’t see much nowadays are “hogs horns”. A relic from the 50s-70s really. As a truly sad person, I’m always delighted by spotting vintage antennas such as hogs horns or Band I/Band III TV antennas. Perthshire/A93 is a fantastic Band I/III hunting ground. Up in Perth last week for Jethro Tull got me very excited at the number of Band I/III antennas on Perth’s buildings. But it’s Blairgowrie that takes the award. H and X Band I antennas adorn the buildings and there must be the biggest surving collection of Band III Yagis in the UK there. Including many installations with twin 8ele Band III yagis bayed. When you consider that 405 line TV was switched off in 1984/85 that means all those antennas are at least 25 years old. Knowing a Scotsman would never waste good money on a new antenna when it would only have a life of 2 or 3 years it’s fair to assume most of those antennas went up some considerable time before 1980. When you consider how big an 8ele Yagi is for 200MHz then either it’s not windy in Perthshire or they were made from the same metal as the Forth Bridge. (The Victorian one, not the 1964 one, that’s falling down!).
