Mobil Radio Meter?

The dosy operate on the same principle, but uses a toroid pickup transformer which has the antenna feed-through passing through it.

...and therefore the internal wiring is not in the signal path, so there's no signal loss because of it.

-ALL- meters have loss, or else every meter manufacture has found a way to defy the laws of physics. if there is no power being removed from the forward going radio wave, what is making the needle move??

8541 - okay. Perhaps I should have said that there's no signal loss that's going to be detectable on the air under any circumstances, and only calculable on paper.

How's that?

you got me there. that is true.
