> 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.
