Default Wireing Cb antenna D21

So I'm trying to find the best way to wire an antenna cable to the rear of the truck for my cb. I'm using either a door jam mount or a sidebody mount to attach the antenna to the tailgate jam so that the antenna is in the rear of the truck. My question is what is the best way to run the cable. Should I just drill into the cab and bed and run it that way? or should I run the cable under the truck along the body to the cab and only drill the one hole and use a thick grommet to close the hole after. I'm planning ti run the cable from the hole to the cb under the carpet once I pick up the new seats next month. The same way I'm running the Xm radio antenna cable.



the advantave of the side body mount is tht the cable would only be run from inside the bed to the cab where as the jam mount I would have to bring the cable from out side of the truck into the cab so i'm not sure what would be better. the two mounts use two different attachments to the antenna.



For those interested

cb. Cobra 29lx
Antenna: Firesitck 2

There are multiple grommets on the cab floor that you can use to accomplish what you are after. I would just put a hole in one and silicone it up after to prevent leaks.

There's a big grommet under the driver's seat. That's what I used to get the wiring into the cab for my rollbar lights and whatnot.

depends on the yr, I guess. mine is under the pass. seat.


As far as the run. Back of the cab is double wall. floor single. bed single at the front and double on the side.

If I were to run it, I would mount it on the center of the roof. This allows for a wider area contact for the base and signal reception. Better reception and the highest point on the vehicle.

A lot of CB cables have an adaptive end meaning you would only need a 1/4" hole for the cable then you can screw on the connector that connects to the antenna. Otherwise you have a big hole for the connector and have to fill-in around the smaller cable.

You can use the bed drain hole and go through the vents behind the cab. The only caveat with that is you'll have to solder on the new PL-259. That way you can also run a flat mesh through the hole from the antenna bracket to the frame. You'll have excellent signal and DC grounds that way, and drill zero holes (except for the bracket). This is the way I run my screwdriver antenna on my D21 (good from 80m-6m).

When I first installed a CB in my former 87, way back in 87, if you still have the factory rear bumper. I installed mine on top of the bumper right behind the dr. side taillight. I used this type of mount ( really worked good) and had to cut a circle in the plastic cover to give it a good ground. This was not the exact mount I used but it is very similar.

can see the antenna, 7' Firestick, (but not the mount) I used to run back than in the pic below (click for bigger pic):







Later on as I got better equipment I switched to a perm. mount Wilson 1000 antenna mounted to the center/rear of the roof, perm. mount requires drilling a hole of course ( ran a magnet mount first but didn't want to take the chance of anyone cutting the cable), never had any leak issues with the hole. Mounting the Wilson 1000 in the roof made it easy to run the cable as it is already inside the truck.



The Wilson 1000 is a very good antenna and you can remove the coil/whip assembly when needed ( comes with a cap to cover the threaded part), plus having an antenna in the center compared to the rear makes the reception/transmit pattern more omni directional. Having an antenna on the rear corner would make the reception/transmit pattern stronger to the front and opposite side of where the antenna is mounted.

I guessi'll have to look into mounting on the roof then. I'm running a 5' firestik. I was just looking at a ball mount that allows for attachment any angle so I might go with that.

I have a K40 antenna That i have used for more than 20 years. It also has a removable load and a weather cap. I ran the coax out one of my side windows (kingcab).

K40's are nice because the end connector comes apart to reveal a smaller connector, useful for going through a smaller hole, at least they were like that years ago when I had one, no idea if they are still that way.
