Yes. Or you can use a TinyTrak or OpenTracker along with an
AntiTracker.

Yes. I have a 50W mobile in my Jeep with a couple of
permanent-mount antennas. Don't recall which I'm using for APRS
right now but I think it's the 1/4 wave on top. I run the radio at
medium power most of the time off an OpenTracker, so that's like 20
or 25W. When I go into the mountains (which ain't far) I sometimes
bump it up to 50W. For the most part in the hills/canyons 20W works
out just fine for me. My commute goes from sea-level to hilly
terrain/river canyons and I do pretty well. The 1/4 wave gives me a
higher radiation angle than the 5/8 wave, so I seem to get out of
the canyons better with it.
