I could use some help? I recieved the cobra 75 wx st CB for christmas. This is my first cb, and have been looking at all of the options for locations to mount it. I think i know where it's going. The problem is every thing else.

1. Are the pos and neg wires long enough to reach the battery from under the glove box?

2. What is the best antenna to use? I was thinking about a 2' firestik.

3. How much coax cable do i need? And what is the cleanest way to run it from the spare tire location?

And anything else that i might have missed?

 

1. Wires are long enough to reach the battery, but you only have to run the pos, the neg you can ground to a body ground post on right under the dash.

2. Most JK owners use a 3 or 4 foot Firestick. Length might be a consideration if you park in a garage. Consider a quick disconnect.

3. 18" coax is just right. run it through rubber grommet on door, tie strap to 3rd brake light wires, run under carpet on right side to the front.

I grounded my antenna to the outer stud for subwoofer.

Consider the adjustable antenna, for SWR calibration.

After installation you should get an SWR meter and calibrate antenna for optimum performance.

 

I ran my power from an open spot in the fuse box, it took me 25' of coax and the 36" firestik ii is what I went with. Mounted it behind the glove box and ran the mic to the right side of the steering wheel, right above my knee....I still need to get a swr meter. Anybody want to loan me theres through the mail...lol, I'll pay shipping both ways.

 

I've had really good results with a 4' Wilson "Flex" antenna on my CB. It's a little longer than the Firestick, but it allows me to get the tightly wound portion of the antenna up completely clear of the tire, top, and cage...and it is also bendy enough that I don't need to worry about trail damage.

 

Thanks for the info on the "flex" antenna.
I was thinking about changing mine out and using the 'flex" type but wasnt sure how well it would work.
Iv got a 4" Firestik but its a little more ridige than I like being it s mounted on the license housing.

 

I've got a serious noise problem on my set-up, and ran the cable similar to yours with the same grounding. Any noise issues?

 

No noise issues whatsoever and good SWR readings (under 2). Make sure the ground wire is actually touching the stud. The nut for the subwoofer is a plastic acorn nut and it is possible it is not touching the stud (and is just being pinched by the plastic part), if you used a round connecter. Might also want to consider using dielectric grease on it to get good continuity.

 

Will check, thanks!

 

Thanks everyone for the help. The info will come in handy.
