Antenna faulty

It looks like my tri-band Par antenna, which should be a good match on 10m, 20m and 40m is faulty.  It is a good match on 10m, but only on 20m and 40m via the ATU. Tomorrow I shall try loading it up as a long wire tuned against ground via the ATU. Somewhere I have a Sandpiper Poliakov vertical that I should erect. As I recall  this has a 9:1 unun so it matches well on most HF bands via an ATU.

Even soldering on a coax is hard work these days! Oh to be fit.

At the moment I am on 630m WSPR using the earth-electrode “antenna”.

    I do not know about your situation but anytime I put together an Aluminum Antenna,I always lightly wire brush the parts that fit together and after I adjust them for best performance I put a light coating of waterproof clear silicon,this has always helped.73

    Can you describe the earth electrode entenna

  • Scott W0SGM:

    Did you tune the PAR ? They come resonate very low in the bands. I had to trim mine to get it resonate where I wanted it. Did you check it with an antenna analyzer to see where the resonate points are ?
