I made my first satellite QSOs with my FT-817ND and the stock antenna
that came with it. That combination was adequate provided the
satellite was at a higher elevation and the downlink was strong and
One drawback, however, was that I had to rotate my radio in order to
hear the signal during a pass but that also meant that it affected my
uplink. There were a lot of exchanges along the lines of "Huh?" and
"What did you say?" during those contacts. I'm sure I missed a lot of
potential QSLs because of that.
Those limitations alone persuaded me to get my Arrow Yagi.
