I use the 910 with one of the KJ6KO 60 watt amps to 50ft of lmr400uf, and a m2 35 element yagi. Circular would be better, but I also use the antenna system for terrestrial SSB work. Fine tuning the uplink is very important on L band. Due probably to radio inaccuracies, and maybe on the spacecraft, I have to offset the uplink by about 3 khz.
