Hi Fred,
I can understand your hesitation. But it should be noted that the ARISS Columbus patch antennas have to withstand acoustic vibration tests of up to 49G. This is because of the launch of Columbus in a Shuttle bay where the boosters induce strong vibrations. The first antennas failed these tests and new are being developed to cope with these constraints. ESA and NASA set very high constraints for the ISS. That has a price.

Pay me for the materials and I will make you a few copies. I can even alter them to your mounting configuration. I am sure Lou and Stan could tweak them for a nominal fee. Materials should cost less than 100.00$ US. I could not in good conscience be a part in any way to paying anyone 100 grand for a couple simple antenna's.
