Rob: I really like it a lot. It's been years since I used a Dremel, but this thing was awesome. Gotten on sale it was cheap and I wanted some more stuff for the new air compressor.
Doc: I did the same thing Rodster did and drilled a hole right-smack-dab in the middle between the factory holes in the mic mount. Then mounted it using the dash bolt. I also used some double sided tape behind the mic mount to keep it from swiveling.
RX: I did not tune it. The thought of pulling all that crap out to do it really pissed me off. However, unlike our old setup, I turned it on and was receiving right in the driveway. That's great because we're a long way from the highway or any truckstops. I didn't receive anything with the old truck.
I did use 18' of coax and ran an extra ground wire on the antenna. I'm sure that has something to do with it.
