[amsat-bb] 15-10m satellite transponders to be launched

[Gary Thomas]

 Years ago, I used a cross dipole for ten with a screen under it. It had a bowl shaped pattern and worked pretty well. For fifteen used a "J pole made of twin lead from a tree. But as one poster noted when the bands were open you didn't need much.

I used a 2 element HF yagi for uplink and downlink (mostly because that's
what was on-hand). I aimed the beam in a general North-South orientation but
as I recall it didn't matter much which way it was pointed. Geeeze ... I was
a youngster back then!
