If you are not convinced just look again what NX4D and myself did in the last 10 years. Doug worked 311 on 160m and I am at 298, but I heard 312 countries on 160m form a city lot, my back yard is 30m x 50m, and most of them worked listening with a pair of horizontal phased loops that I call HWF. Today there are over 50 station around the world enjoying the same kind of results with HWF. My webinars on WWROF have all you need to know for a jump start.
A technical question about these antennas, not withstanding the testimonials. Why cascade two preamps? Is it not the case that the amplified front end noise of a single 2 dB NF preamp will overcome the receiver noise of any reasonable radio? If this is correct, how does adding a second 2 dB NF preamp in cascade make any improvement in signal to noise ratio? Regardless of what the antenna characteristics are. In both cases, the antenna is looking into -171 dBm/Hz of noise floor. Rick N6RK _________________ Topband Reflector Archives - http://www.contesting.com/_topband
