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 horizon.
This was a crude test and I didn't use any formal measurements in my assessment.
Overall I would not recommend this antenna for circular polarity satellite use. For terrestrial vertical / horizontal operating I'm sure it's okay.

I just acquired a "new" in the-box, never assembled Crushcraft A144-10T "VHF Twist" antenna. It includes the cabling to allow the user to select left or right hand polarization. My questions are numerous:
1.) How is the performance on this antenna, compared to more modern designs?
2.) If I were going to install it inside my attic, should I chose left or right hand polarization?
3.) Any caveats or things to watch out for?
Any information that could be provided would be great. I was thrilled when a friend stopped by and asked me if I'd be interested in the antenna. Good price too.
