If you don't need to use a glass mount antenna, don't. They work, but not as good as something hard wired. Cell antennas are easy, if you were mounting a ham radio I would recommend a FlexiWhip, those things are amazing. I go through parking garages with mine and hear it smack into the beams all the time, but it's super flexible so it doesn't damage anything. I have an 800mhz antenna that's about the size of a film canister, and I don't think the cell booster antennas are any bigger. Make you sure run any coax behind the airbags, you don't want even more things whipping at your face if you ever need them.
