As for mounting the antenna the top is the best place for it in case of best TX. If you put it on you fender or either side of the bumper it tends to be more directional than if it's mounted on the middle of the top. If you have a bridge-buster the only place would be the rear bumper but if you go with a firestick or one of those shorty's I'd recomend puting it on the top 10" from the rear and in the middle. I't also looks nice like that, I have 2 like that on mine, 10" from the back and side sitting side by side.
