[Lowfer] Loop Antennas for Transmitting

Yep, 50x50 and they put out one heck of a ground wave. Bill gets good
skywave reports, and I haven't been lucky yet to have good propagation to
Mitch's. Bill is using a better wire for his conductor; I am using the basic
#12 to get on the air for now. He say's RG-8 coax (using the shield
conductor) works very well. It is heavy though. The lower the AC resistance
of the conductor, the better current you get which is in proportion to the
radiated signal. I think I have the right.

Subject: [Lowfer] Loop Antennas for Transmitting

Not to open a can of worms, but could we discuss transmitting loops
in general terms?

Based on their use on the 160 meter band, they seem to be poor
performers as compared to short wavelength verticals. Lots of antenna
current, but poor radiation.

Can someone explain to the village idiot (me) why they would perform
any better on LF, than they seem to on the MF bands? My understanding
is that Bill's design is basically a single turn vertical loop that is tuned
to
resonance, correct? I'm assuming something like 50 foot in circumference?
