Hi Stan
I own an AlexLoop and a few of us hams went into a park and did some
signal comparisons on 20 meters. We compared an
Alexloop, a full size vertical with four radials, and a 1/2 wave end fed
for 20 meters.
I used an a/b switch on receive and transmit.
The vertical beat out the other antennas by less than an an s unit. The
Alexloop was almost as good as the full size vertical. The only drawbacks
I see with this antenna is that it needs to be in the clear. It also has
a very narrow bandwidth maybe 30Khz.
On a SOTA activation making phone contacts on 20 meters was quite doable
with 10 watts last year. You will need an SWR meter with a needle to
catch the quick dips as you tune the loop.
bye Richard
