Last weekend I took the time to experiment with the ATX-1080 antenna. My expectations of this type of antennas have never been high. Now I have a somewhat different view.
In the
limited manual of this antenna is discussed by making a counterpoise for them as possible to function. This manual is a guideline given for each band. After some soldering,cut and try, I came to the following lengths:
A counterpoise for 20M, length approximately 3.9M
A counterpoise for 17M, length approximately 3M
A counterpoise for 10M, length approximately 2M
30MAlmost 3 segments of the telescope extended, counterpoise for 20M in use.
20M10 segments of the telescope extended, counterpoise for 20M in use.
17M5 segments of the telescope extended, counterpoise for 17M in use.
12M8 extended segments of the telescope, counterpoise for 10M in use.
10M10 segments of the telescope extended, counterpoise for 10M in use.
During these experiments, I made a few QSO's:
9A2YM (20M cw)
OK1AUZ (20M cw)
UA1CE (20M cw)
SV2HJQ (20M ssb)
On the Friday before I made 2 QSO's with Lithuania on 30M.
At all QSO's I had an output of 2.5 Watts. My FT817nd was on the dining table (
see) with rear mounted antenna. The counterpoise lying on the ground.
