I have very little room for antennas, so I use polarization diversity. I have a short groundplane (originally intended for 17 meters) which I use for diversity together with 40 and 80 meter dipoles. I use the K3's preamp with the groundplane, and normally use the attenuator on the 80m dipole. This is a big help with weak cw signals on 40m, less so (but still useful) on 80. On 20m I have a beam, and since the signal is always much better on the beam, there's no advantage from diversity. Sometimes it is useful to check if I'm hearing a signal via long path without rotating the beam. On 160m I have a small ferrite loop which I use for diversity together with my transmitting antenna, a vertical. I have an external preamp for the loop and I use the K3 preamp too. I also use the attenuator on the vertical. It helps a little, but there are lots of better 160m receiving antennas like the K9AY and Beverage. -- Vic, K2VCO Fresno CA http://www.qsl.net/k2vco/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
