Now this is something I have a little knowledge on, just some, not all. I personally run a Cobra 19 ultra, it was $35 at walmart, and it fits nicely between the seat and center console in my burban, no drilling holes required. Its nice to start with, but it is limited. I also have it set up so I can plug it in to the power point, instead of running and splicing into the wiring. Now for an Antenna, I started with a 27" fiberglass whip from Radio Shack, comes with the magnetic mount and 16' of coaxial. That worked well for the first 10 mins, and with 1800 miles on it, and nothing but static and bits and pieces here and there, that went out the door. So I ended up with a 102" Stainless Steel 1/4 wave whip from Radio Shack. I used the mount from the 27" and rigged it to fit, then stuck it between the back rails on the roof rack so it would not fall off. It dose not stand straight up, but it has that layed back look, which shortens the overall height, about 15 feet or so when its straight up. Its not the perfect set up, and I have to fiddle with it from time to time, but it works well going up and down 75 and 95. I can pick up guys on the east coast of FL form time to time. Average distance I get is about 10 miles I would say, maybe more. I dont use mine really, but for traffic, the po po, and for something different from the radio, 24 hours of driving straight you tend to hear the same crap on the raido. Its not my Ideal set up, but its working for now until I can get another pickup. If you wanna go all out, you could get one of those Cobra 29 LTD BT 40 Channels, with Duel 102" whips. Thats what I am going to end up with one day here soon.
