> Concerning your real experience, how did you measure the elevation angles and pattern beam width? Peter,
We did not measure any angles, I was barely getting started on 160m at the time, and was more interested in putting up a good antenna for the Contest. The radiation pattern information comes from the ON4UN book Low-Band Dxing/Vertical Antennas/Tall Verticals. We had a similar setup as his example 60+ radials over average ground for each antenna. Our location was here: 35.335581, -120.747388 RF, I can set up a 5/8 wl vertical over salt water, and I am pretty sure I will have a killer ground wave signal in ... Santa Barbara. As far as the really low takeoff angle I remember seeing a table, I believe it was an ARRL publication where signals on 160m 90% of the time arrive at an angle above 13 degrees. This is from memory, correct me if I am wrong. Niko AC6DD _________________ Topband Reflector
