I can find lots of cheap and cheerful UHF (terrestrial) signal
strength meters for checking aerial alignment etc. but I can't find
any VHF ones (for radio, band II is it, 87.5-108MHz). Are there such
things at the sort of under a tenner price the UHF ones are?
The GY560 frequency counter works down to 50MHZ. By
measuring
at a distance you can get a rough signal strength value.
By measuring at a distance from what? I'm after seeing how much
signal is coming down from an aerial.
Have you any attenuators? Resistor network? Alternatively
construct an LC aerial to radiate? Just a couple of thoughts.
If you're looking at something for about £10, it will be something like
an untuned high-gain wideband RF amplifier (with a bit of bandpass
filtering in front), driving a rectifier and a meter (which is
essentially what the terrestrial TV and satellite finder meters are).
I don't know of anything, but I suggest that you ask in
uk.tech.digital-tv.
