Hi Les, N1LF
To built a polarization switching for a crossed yagi Cushcraft
A144-10 T is unpractical because the antenna and the phasing
harness are using PL connectors and the coax relays are normally
supplied with N type connectors.
You can't remove the PL connectors from the phasing harness
be
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
To make a long story short.
Try it before you spend more money. It probably will be a good antenna for
your attic. No water issues at that location. Set it up for LHCP and with
the current satellites it will work most of the times just fine.
Why pay big bucks for a "newer" one if this will work f
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 i
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 polari
