marcspaz Posted July 6, 2022 Report Share Posted July 6, 2022 Hey folks, I have a quick question. Tonight I made a 1,700+ mile contact from Virginia to Mexico using the ISS cross-band repeater (VHF/UHF). I was running my Diamond X300 vertical which has 7 dBd gain (9 dBi) on UHF and my frontend was getting overloaded to the point where a lot of audio was distorted. I was watching the tracker and I could only hear well when I was on the edges of the coverage area, near the horizons. However, one person sent me an email saying he could hear me very well in Mississippi... so I know the take-off angle and the doppler effect is accounted for. Does anyone here do satellite work? I'm thinking I have too much gain. I am considering building an omni-directional horizontal loop and trying again soon. With the exception of buying a beam on a tripod, do any of you have any advice on what to do for antenna design? What has worked well for you? Thank!
