Hi. I am currently working on the microwave patch antenna's for Eagle with Lou Mc Faddin W5DID and Stan Wood. 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.

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.

Think of it as a donation to have a L/S system built, launched and have human spaceflight certified. It is much more than just the cost of the hardware for the antenna. Have you looked at the total cost for Eagle for comparison? This is a bargain.
