[Lf] Re: [Lowfer] Loop antenna help please.....

By golly, it sounds like you ran smack into the VE2IQ loop trick.

The last time we spoke of this, he had run a long wire around
a very large circle ( acres ) and tuned on the far end for resonance,
sounds like a nice 'probe'..

Seems like you have a nice directional array ( DA)

You are having more fun than a lotta hams.
How are you matching the loop to the amp?
