What device to get the best reception from an externally mounted t.v
aerial. I think its a Yagi type. Basically the position moved some time
ago, due to high winds, but was never rectified because there was a
signal from a different source, but now the external aerial is needed.
The device you need is an engineer with analyser. You cannot get away with a
misaligned aerial. If you amplify a poor quality signal, you will get MORE
poor quality signal. No amplifier can find something that is not there,
amplifiers are for overcoming losses.
Total ******** as usual from the usual TV erection spammer.
Plug a TV in and wiggle the aerial until you get acceptable signals on
all available channels.
I AM an engineer, and believe me, you can get bogged down in dials and
scope traces far too much.
In the end its a quality picture you want, not some arbitrary reading on
a meter.
