CB antenna (stock tire carrier mounting)

Thinking about drilling a hole in my stock tire carrier and mounting my antenna to it using the antenna mount i made....

I recently built a DIY ROKMEN rear bumper and had to eliminate my previous setup (pics below).

Now i want to mount from the tire carrier, what are my options and whats the best way to route my coax from a location on the tailgate.

Thanks

I like how this guy mounted his, i could make something like this work for me....but he painted the mount all the way around and didn't grind either the tailgate or the mount for a good ground connection....should there be some grindage going on here..

It's not a stock tire carrier, but you get the idea on what a 4ft Firestik antenna looks like mounted up higher!

It whips back and hits the wiper, doesn't really hit the window, if it does it's not hard enough to break it! Mine whips around alot because it's mounted on a spring.

I'll have to post some pics up but i took the mount i had on my bumper and relocated it on my tire carrier. Looks sweet, very tall.. Idk why but my CB was getting SWR readings of 3.5 or more. I re configured my nylon washer from the top of my mount the to bottom and i am now in the 1.5 - 1.8 range. so it goes (antenna/lock washer/flat washer/metal antenna mount/ nylon washer/ stud mount.) Is that correct? i am gettin a great swr reading at this point, before i had my nylon washer above the antenna mount on the bottom....and would get a pegged swr meter.

antenna is the same setup as below except i have the nylone washer below the metal mount, with the flat washer touching the top of the mount. I get a 1.5-1.8 reading between 1 and 40. Is this a true or false reading....?

....maybe this is causing a short situation and is why im still recieving a 1.5 reading but it is through the jeep, vs the antenna....

Looks like it should be...antenna, lock washer, washer, nylon washer, mount....so I think you're correct now. The nylon washer is your insulator and if I remember right, you want to prevent the antenna connection from grounding out on the mounting bracket.

That nylon washer MUST have a rim (hole size) that protudes into the mounting hole and insures complete mounting stud/bolt, insulation from the metal mount

Nylon top and flat nylon/nonmetalic washer underneath

There's a way you ohm out the cable to make sure it's installed properly...you're actually supposed to do that BEFORE you install the antenna so you don't screw up any components in your cb. I tried to look for it, but I couldn't find it. I'm thinking Firestik's site has it in an article somewhere.

According to one article I found online...easiest way to check for a short is to use an ohm meter between the cb antenna mount and the center pin on the cable. If you get any continuity, your antenna is shorted (meaning your washers aren't installed in the correct order).

Sentenced - the picture above is not how the antenna is setup now. They nylon washer on top (in the picture) is now on the bottom, below the mount.

but i recieve a 1.5 - 1.8 reading with my swr....

By the book this is not mounted correctly, but it seems to be working....

Jimbox - from what you are saying, maybe i should bore out my hole a little bigger to insure the stud isn't touching the metal mount. And if possible to add another nylon or rubber washer below the mount and move the nylon washer back to its original position. That way i have a nylon nut on top and a nylon nut on the bottom, and my antenna is not touching the mount (for sure) because i bored a bigger hole.

Yea, a nylon FLAT washer top/bottom won't work (maybe) the top washer should be able to KEEP the antenna shaft, from EVER touching either side of the mtg hole

Go to radio/Radio shack shop and have the (technition) (?) show you what I'm talking about and they will also have the special nylon bi-level washers for just that purpose !!

i understand what you mean about bi level washers, i think that is an awsome idea. But what i never knew about was not letting the antenna stud touch the mounting hole. So i will put the nylon washer back in the correct locatioin, bore out my hole a bit bigger and see if i can get the stud not the touch the mount.

I bet when i was running into issues before that stud was touching my mounting hole, it was something i wasn't watching out for, and didn't know to look out for....

Good luck, but remember, you'll need a non-conductive washer ABOVE and BELOW, you don't want the nut/washer touching the mount either

Be careful, you can burn out the CB output circuits by transmitting with a grounded antenna
