Can anyone recommend an antenna...to improve my [mobile] satellite reception?
By definition, a good antenna for repeaters is bad for satellites. Repeaters are on the horizon, satellites are usually higher when they are strong enough to hear.
And don't overlook the feedline. While I was running a high gain tri band whip for the mobile, I used to get good results from AO-51. A clue could be found in the antenna system. The antenna was a 2m/70cm/23cm whip, and for 23cm performance, I spend the money on a factory made mount/feedline, which was designed for 1.2 GHz use. The result is that at 70cm, this antenna outperformed the other 70cm capable antenna (which was fed by about 10' of RG-58) by a noticeable margin, and satellite reception was better than expected for a vertical with gain.
I wonder how this feedline would have performed with a 2m 1/4 wave whip. I suspect the results would have been superb.
