I had a buddy take his and slightly modify it. He took the vertical set
and optimized it higher in the band. So he had a Horizontal for SSB & CW
SWR great at the bottom of the band, and a Vertical resonant higher for
FM work, and Circular for sats, and the slight mismatch diddn't seem to
hurt it any.

I have a Cushcraft A144-20T. Twice as many elements in each plane than
yours. I run both a vertical and horizontal coax to my shack and use a
crossover coax switch with phasing and impedance matching coax to
generate switchable circular polarization in the shack. Works great
for me. The polarization change makes a big difference at times on the
satellites..
I can also run just vertical or horizontal polarization by changing
the coax configuration in the shack. In fact, you can use the same
crossover switch as a SPDT to experiment with changing between
horizontal and vertical polarization. I do this during VHF contests
sometimes. I have also worked meteor scatter with it.
I have been using this antenna for 25 years with no problems. I used
it with AO10, AO13 and AO40 with no problems. The low orbit birds are
really loud compared to the high orbits birds.

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.
