It is for testing HF antennas, but no reason it can't work for VHF as
well.

After writing this, I was thinking of the G5RV, it has a cloverleaf
pattern so it might register as a loss since the antennas would be
broadside to each other.

I don't know the distance for the FSM. I suspect it would have to be
a good distance away. probably a wave length or more.


This would work best with a beam antenna as the lobe would be
consistent. but a 3/2 wave antenna would have different radiation
lobes so it might register a loss instead of the gain it actually has.

It is a thought, but I may have to reconsider it.
