EZNEC agrees closely with your previous values.

OK Cecil, thank you for the test.

The question now, is, why a GPA in free space does not present a 36 Ohms
impédance ?


I use a full sized GPA on 40m, 6 meter high and a quasi 1/1 SWR with 50 Ohms
coax line;
with 36 Ohms in free space I had 14 Ohms for losses in the ground and 36
Ohms for my correspondant;
but now, it is 28 Ohms for the ground and 22 for the QSO...


To night, I can not open your page www.qsl.net/w5dxp/dipvsver.htm

I was interested to see if you get the same results,
I use also a half wave dipole 16m high and the GPA, with a slight advantage
for the GPA during the night and distant stations, and the opposite during
the day time and short distances;
the ground is very poor here.
