Quarter wave vertical is not good antenna for serious DX, I suppose. Compared to 3 el yagi at 300f ;-) http://vimeo.com/27737232 But Wellbrook antennas are good also. Timo, OH5KW At 19:18 -0700 11/4/12, wb6r...@mac.com wrote: On Apr 11, 2012, at 12:23 PM, W2PM wrote: Nice for nulling

I would not be too quick to dismiss small magnetic receiving loops from consideration for DX work. I used a coax diamond loop, 5 feet on a side, on a rotator at 20 feet, prior to trying larger wire loops. The small loop enabled many contacts in Europe from my West Coast city lot. The signals

Topband: Magnetic loops

2012-04-12 Thread D. S. Coleman
All: I can comment on my experiences with a magnetic loop, as I have one, along with three one-wavelength beverages, and a pennant terminated loop. Each of those antennas, at one time or another, proves its worth as a receiving antenna at my station. In terms of signal to noise ratio, the

Well, my Wellbrook might work as well yours, as I too have worked CE/K7CA with mine on 160 from the Black Hole of KL7. More than once as well. For me the magic isn't directional gain, it's the improved S/N and the ability to null local single point QRN. If I were able to extend a Beverage or
