First of all, excuse me if this question is too basic: I feel like it shouldn't be a struggle to understand, but the fact is it is.
We put up an antenna to play with radio a little, and someone we were working with showed us that there's a reading on the voltmeter without any of the equipment hooked up.
We are in a city, so there is wifi and power lines, and we're doing old-fashion analog testing to try to reduce the voltage before connecting everything.
The interesting part to us is that when we isolate the antenna by laying it on the shingles, then connect it to ground with the voltmeter plugged in in between, we get a reading of ~4Volts AC (it changes as we move it in relation to the power lines or wifi antennas).
However, if we lay it bare on the ground while still connected to the voltmeter, the voltage drops right off.
The question is: Is our test flawed in some way?
And; though it sounds ridiculous as I pose it: should we consider installing the antenna on the ground permanently?
Thanks in advance
