Finally got everything together and finished up my install. All told it turned out pretty nice looking. I used a FireStik II 3 foot antenna mounted in a hole at the center of the trunk. I routed the cable from the trunk behind the quarter panel, under the door sill, and then across the dash underneath the glove box. For power I used a fuse tap off of the "AUX" fuse (20A, but I used a 3A for the radio's circuit) and grounded it to the firewall right next to the fuse compartment on the passenger side. Haven't checked my SWR yet, but when I get a hold of a meter I will definitely do so.
As far as performance I'm pretty happy thus far. I've had no problems with people hearing me, although during rush hour in the city I don't even bother trying. My first impression is that this thing will only be useful either late at night or on less-traveled highways. On my daily commute I can never hear anything but static and the occasional person that can punch through. Several bears went unreported (or at least I couldn't make it out). I did get a chance to use it to and from MSU last weekend (3.5 hour drive) and was VERY impressed with how easily I could ask for bear reports and talk to people. Several warnings were 15-20 miles in advance.
