If I recall, a full wave loop has an impedence of about 100 ohms, so if you
feed it with an electrical half-wave length of 75-ohm coax, you should have
an acceptable match, and a decent vswr.

I'm starting up an old project that I never quite finished - my loop
antenna.

When I first put it together, I tried a simple loop of coax to couple the
radio to the loop. Was never really satisfied with that though.

I'm wanting to try a gamma match, possibly something a little like what
Owen Duffy posted a nice version of.

The Gamma match is fairly understandable to me, and I expect it to work
well.

What I am wondering about is in the coax loop coupling system, how is the
best match obtained? Loop size? orientation? Luck?
