Well, I decided against drilling a hole anywhere on the pickup. I don't give a rip the old truck being affected in value. I don't want some jackass I don't know trying to charge me a ridiculous sum to install this wonderful antenna.
For a Chinese made product, it sure works very well. I drove at to IH35 without setting the SWRs. I asked for a radio check. I heard it loud & proud from the 328 to 339-mile marker on IH35, barefooted. He said my signal was strong. So, the advice of mounting this on the left fender worked great. I can damn sure tell a difference in reception, thus far.
Why do I know this will likely work? I've owned around 3 or 4 Tram 3500 CB antennas with the 5-inch magnet with the rubber boot.
One day, I might climb the ladder of American made antennas, but for right now this one kicks arse.
I bought a no-hole mount, using existing bolts on the truck. It worked perfect.
Thanks for the help.
