This is my portable setup, the only thing you don't see on the picture is the FT817 and dc supply.
35cm with well tuned helix 5.25t and with 6W only, i have 3dB less sig in peaks then upper beacon some weeks ago,so before the wider bandwidth we have now on the transponder.
It's working better then the patchfeed. I have made a comparison list with different antennes for uplink, i will post it here later.
Hmm, looks file is to big, need to change size first.
