I have a small mag mount antenna, Cobra AT-35, that I'd like to use. It's
about 2 ft tall with a 3" base - center loaded. Has anyone used this or a
similar antenna with a small amp. Cobra, of course, doesn't give it a
power rating but I'm looking for a practical limit. I'm also afraid of it
causing RF problems to the car's electronics because of a small base.

I doubt you'll be happy with that antenna. Look at a Wilson.
