BJ,

I would venture to say 'if' you are using the Loop Antenna for
both Receiving and Transmission then a 1:1 or 2:1 Balun would
work well with a Coax Cable Lead-in-Line. An Antenna Tuner
would be required for Multi-Band operation.

"IF" the Loop Antenna is going to be used as a Receive "Only"
Antenna with a Coax Cable Feed-in-Line; then a 4:1 or even
a 9:1 Balun could be used with good Multi-Band results.

Thanks RHF, and everyone else too - these are great ideas and links.
I have managed to obtain quite good results on most of the bands from
6 MHz and up, and so I was going to concentrate my efforts with this
loop on the tropicals. I was going to start with about 220' of wire
in a loop around my rooftop and off into some backyard trees.

Based on what I've seen here and on the websites, it looks as though a
2:1 balun might be perfect, but a 4:1 may work about as well for a
slightly broader frequency coverage on a receive-only antenna; so I
may try these two first and then compare. One website says not to
use a balun at all (why?), so maybe I'll try it unmatched too.

I will post some observations when I get this thing up and running.

Thanks!
Bruce Jensen
