My best place to add an antenna for CB would be the hood of truck, does the antenna get any feed back from the front overhang of TC and will the TC interfere with the SWR of radio. I know this is a question about CB's, but need the experience of TC owners , who would know the ans........Thanks

Lots of good tech help here:
Firestik
Cab Over CB Antenna

I had a lot of trouble finding a spot for my CB antenna. I may go with a magnet antenna on our new truck and put it on the cab, them move it to the front bumper with the camper in the bed.

Good Luck,

I run a 5' firestik on the fender (in crack between hood and fender) about halfway between the windshield and front of truck, and my camper is always on. My SWR are about 1.3 to 1.4. When I was installing I temporarily mounted the antenna in several places on the fender (More to front or back) with vise grip and I could have even gone a little closer to the camper before it started to effect the SWR. It is noticeably directional in town but on the highway it is fine.

Before the firestik I ran a Wilson 1000 hardmount on my spare tire mount which was off the front bumper, so basically centered at the very front of the hood. SWRs were low but for whatever reason it sucked. It had no ears either.

I considered putting an antenna on the roof of my aluminum camper either a conventional or a NGP whip but I didn't want to add much height so that kept me to a 2' or less whip. I think a 5' whip on the fender is way more powerful with way better ears than a 2' whip on the roof even if it is a little more directional. Just my opinion though I may be wrong.

I ran dual center loads on my mirrors on my big TC. I had to make up some pvc spacers to angle the antennas away from the cabover to get the swr back down. The mid-mounting point did give me good reception to both the front and rear. If it is a permanent TC installation, I'd condsider moving the antenna(s) up on the camper itself. If it is a metal shell camper, it will act as a good ground plane. Otherwise, you will need a self-loaded style antenna, bottom or center.

I used some silicon adhesive to cement a metal plate to the top of my camper, then use a magnetic antenna. The problem I ran into was hitting a branch or something and knocking it loose.

Thanks everyone for your answer's and help, Brad those link's you gave me , helped me to make some decisions about a radio. My real concern was swr reading's and getting it set right.

A neat looking set up Brad, are those the kind of ant. that need no adj. for swr. I am still thinking about hood mounted ant. so as to hide the wire.

Hi Patj
I am considering a mounted ant. in the crack on the hood just as you mentioned, 30 years ago I had cb equip. swr meter and all that stuff, now I have forgotten all about swr and all that, is 1.3 to 1.4 good, on the road is your reception better ahead of you, than behind you. Did you make a bracket for the hood or can you buy one.

This is where our antennas ended up on our current camper. They work great, but they are a pita to hook-up each time. I forgot to unhook them last time and ripped one of the coax plugs off.

No, you have to adjust the tips for the lowest SRW, but it's easy.

But by having 2 antennas, I don't have a problem with not having a good ground plane, because they use each other as the ground plane. Or so the Firestik Tech Info says. With that, I have said more than I know about antenna theory. [emoticon] [emoticon]
