I have made numerous AO-85, 91, 92, and SO-50 contacts from my truck, mostly while stationary due to the desire to log the contacts, with a 25 year old Kenwood TM-733a (~25 watts) and a dual-band antenna on the roof of the truck. Even a simple 2m quarter-wave works fine and offers a decent match on 435 MHz.
The feature that helps the most is the radio's full duplex capability. When I hear my own voice on the downlink frequency I know I'm hitting the bird.

I am hoping to get into mobile satellite operations soon, and at times I will be able to operate portable with a dualband yagi antenna. . Other times, though, I will be on family trips and unable to stop for satellite passes, so would have to operate while in motion. Are AO91, AO91, and the XW-2 satellites able to be worked using a 1/4 wave or 5/8 wave dualband mobile whip antenna?
