Quarter wave vertical is not good antenna for serious DX, I suppose.
Compared to 3 el yagi at 300f ;-)

But Wellbrook antennas are good also.

A lot of us are of course interested in the results of these experiments
because the loop is small enough to fit into a typical suburban or urban lot.
In evaluating the performance of these antennas it is interesting to hear about
one's ability to null out a local Am broadcast station. However t
I do not use LED lights so far at my home as they are much more
expensive than the CFL's but I have found a good use for solar powered
LED strings. After the outside Christmas decorations were taken down I
had a bunch of solar powered DC LED strings wanting to find some usage.

BCB work would be good for the Wellbrook and I suspect that is their target
market.

Dave,
This is a great topic as there are a lot of us on small lots active on
topband needing what ever edge we can find...
Do you have this loop you've designed published where we can see it? I know
as a low power backyard set up with a MA160V, it would be interesting to
look into.we
I made some signal to noise measurements last night between my short BOG
and LOOP. Local (100-300 miles away) cw signals. The Loop, which is
still living in my basement, is within 3DB of the BOG. I will move it
outside soon and see what happens to SNR. I still need to try it out on
some weaker DX
