[QUOTE="spiney, post: 114345, member: 192438"] But, why? The simplest type works as I've said above, an IC rf amp feeds an ac millivoltemter (simple moving coil meter configured as ac milllivoltmeter, that is, in a "diode bridge" circuit, look this up if you don't know it). Operating power for amp is taken from the sat receiver's lnb supply. But, this is microwave frequncies, so it's striplines, metal cans, etc, such stuff is usually made in factories, with "home construction" it probably wouldn't work at all, unless you're extremely skillful!
