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
