[amsat-bb] Mobile Sat antenna

Hi All, I have heard a couple times on the FM birds of stations signing mobile. I wonder what type of antennas are used for mobile. I have an Arrow I use portable with my HT. I have a full duplex Icom FM rig and could just barely hear HO-68 on a Wednesday pass up in Em95. No preamp or anything yet and just a 1/4 wave duobander. What would it take to operate truly mobile from an antenna standpoint. Just playing with the idea. I travel a bit during Spring and Summer and might be fun to try.
