This past weekend I built a Rybakov antenna in the field for a Parks on the Air activation at Minute Man Historical National Park. I got a ton of distant contacts on 10 and 20 meters in a little over two hours.

On my site I share my build, some photos, a map of my QSOs and my SWR readings. The antenna performed great but the SWR wasn't great on some bands.

I'd love to hear from you. Have you tried a Rybakov?

@chrisfarnham If your antenna analyzer can read complex impedance (R +/- jX) those numbers do tell the antenna's operation, if you measure right at the feedpoint (using a super short coax).

@ab1wx Thanks for the response. You've given me some ideas for additional analysis on future outings with this antenna.

I was surprised at the high SWR on 20 meters because it performed really well.

@chrisfarnham SWR is merely a "measure of mismatch" re 50 ohm and it has nothing to do with the antenna performance. There are 50 ohm antennas that won't radiate well, and many antennas perform very well far away from 50 ohms. The next question is how you feed those non-50-ohm antennas most efficiently. You are a local, and I am happy to tell you more about it.
