Someone gave me an old but new-in-box version of the same antenna a few
years ago. I did a shoot out between it and the three element Arrow. I
used a ten degree AO-7 and a two degree VO-52 pass for comparison between
mode B satellites.
My tests showed the Cushcraft in RHCP did not perform better than the
Arrow. In fixed horizontal configuration, I saw a slight improvement with
the Cushcraft. In both antenna setups, I had the antennas fixed at the
This was a crude test and I didn't use any formal measurements in my
Overall I would not recommend this antenna for circular polarity satellite
use. For terrestrial vertical / horizontal operating I'm sure it's okay.
