I have short 2 footers in there now, and that's what I normally drive around with. I use them because I can get in my garage without having to take them off. I have a couple of 4' Firestik Fireflys that I use when I'm on the road for a long trip. My radio is hopped up a little, so I only receive or talk for short bursts (if i have to) while the short ones are in. It works well with the weather radio and the short antennas. Even with the short ones, the SWR's are right around 2:1. That isn't good, but won't hurt my radio if I have to use it. The passenger antenna is a dummy.
