Admittedly, there would be losses because the VHF/UHF antennas are not even closely matched, but would this matter with the signal powers involved? To further the question, what about satellites that might pass between a geostationary power satellite and its ground station? Since these u-waves are highly directional, I doubt that there would be large amounts of power distributed outsided the antenna location, but wouldn't even a ridiculously directional antenna at those power levels spray enough u-waves all over the southwest (say), to foul up all manner of u-wave transmissions? Maybe this is cheap to fix (relatively speaking,) but there are billions invested in u-wave communications that might not be able to co-exist. David Pachura {harpo,decvax!cca!ima,esquire}!inmet!dwp
