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
Almost 3 segments of the telescope extended, counterpoise for 20M in use.
10 segments of the telescope extended, counterpoise for 20M in use.
5 segments of the telescope extended, counterpoise for 17M in use.
8 extended segments of the telescope, counterpoise for 10M in use.
10 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.
