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?
