2016 Ford F 150

I'd drill the appropriate sized hole right in the middle of the roof and mount a Wilson 1000. If not that you might make a 'L' shaped bracket for the front fender. I haven't had much luck mounting an antenna on the bed of any late model truck. If you bond all four corners of the bed to the frame it might work.

 

i had a 2008 Ford F150, what i did was get an antenna that stick to the back window and the coax end also glued to the inside window and they could signal to each other wirelessly. The antenna was only about a foot long but i liked it because I could fold it down to back into the garage.

 

How far was your range? EDIT: I can't imagine it was very far. Probably similar to a hand held rubber ducky? Sure 1 foot is bigger, but lots of loss through the glass. When I was new to CB, I thought that was a good option-- no drilling to mount. Fortunately, I quickly discovered the magnet mount antenna. Complete use of coaxial cable *and* RF coupling to the metal vehicle.

 

I would drill a hole right in the middle of the roof preferably right behind a dome light where you would have easy access to it.
I would disassemble the dome light and see if you have a single layer of sheet metal behind it.
Otherwise you might be stuck having to remove the whole interior just to get the headliner out to drill a hole somewhere else.
I put a Wilson 5000 roof mount on a 2002 Chevy Avalanche and it was pretty much a five-minute job and all I had to do was pop the dome light out and pop a hole right through the roof and I fished my coax to the side with a coat hanger and it was pretty much done in 5 minutes without removing any of the interior of the vehicle.
On my Chevy Tahoe I didn't get so lucky and I had two layers of sheet metal behind my dome light so I had to remove the whole interior of the vehicle including all of the seats just to get my headliner out.
Needless to say it was an all-day job on the Tahoe

 

not going to work worth a #### as Craig noticed on his Freightliner Cascadia. nothing beats a flat sheet of sheet metal directly underneath your antenna

 

I used a fender mount antenna on a Chevy. High noise level coming thru antenna so bonding is next order to see if it will solve that issue. You may have better luck.

 

Popping a hole right in the middle of the roof for a Wilson roof mount will increase the efficiency so much over a fender mount that it will almost be equivalent to adding a thousand watts to your system without actually doing it
