Check this antenna - equivelant of a 6 meter halo, by K0FF

and, those are more like 1/2 wave loops (dipole), than
full wave loops (which are very high impedence-hard to feed).
but what you describe is why 6 meters is called the MAGIC BAND
(when its open, its OPEN)! Jim NN7K

I'm trying to improve my 6m antenna situation.
The antenna has to be horizontaly polarized and
omnidirectional.

I'm currently using an inverted V @ 10' & 14w.
Last week the band opened up and I had a strong
SSB qso into northern Canada, a distance of about
1,450 miles and off the end of the antenna, to boot!

I'm thinking - heck - if I can do *that* with such a
minimal antenna, what would happen with a loop
or halo at 40'? I was thinking about getting a OA-50
from Par electronics but it dawned on me I could
save a lot of bucks if I just made a full wave loop.

I don't know the design of the OA-50 - would a
full wave loop perform better? I could make a
horizontal loop with support for $10 easy.
