Attic dipole vs attic vertical using WSPR

20 meters with dipole
Saturday afternoon I had a chance to compare the 20 meter attic dipole to the attic vertical (High Sierra Sidekick) using WSPR. I tried 40 but there was lots of CW action and some local noise that really did not allow me to do a good comparison so here are the 20 meter results. The power output was 4 watts.

  1. Hi Mike, that's a big difference. Does the vertical radiated enough? Have a nice Sunday. 73 Paul

  2. Hi Mike, I'm surprised the vertical is worse then the dipole. Did you expect that? 73, Bas

  3. Yes I too was surprised at the results but as the day went on the vertical did make it into Europe. With the vertical I know can get up to 80 meters. It may not out preform the dipoles but I have full coverage of the bands now. I do remember reading how attic antennas were not all that great but I have the results to prove that wrong. I will look into the antenna more and see how it can be improved

  5. It does seem the vertical is not the antenna for the my attic installations for sure. Great I can use this program to do the comparison it saves me lots of operating time used for tests.
