I received my CB yesterday and now its time to get an antenna. I have the Teraflex spare carrier and it has an antenna mount built into it, however the mount is only about 30" from the top of the JK. If I go to a 3' antenna, it will hit my garage door and roof of my parking garage at work. Yea I know, "JK Problems", but I would like to continue to use my garage and covered parking at work. What is the basic rule about CB antennas: the longer the better? Will a 2' suffice?

I take my antenna off to get in and out of my garage cause I only use my CB on the trail. The shorter you go, the weaker and shorter the range. If you are always in a group where you are close, that sholdn't be an issue. In an emergency situation though, your range will be several miles shorter than with a longer antenna.

Bummer... Thanks.

Yeah, I would go a minimum of a 36" Firestick. Much better is the 42" or 48" Wilson base loaded.

Just strap it to your High Lift or install a couple P clips inside and only put the antenna up when you're heading out to go wheeling.

Or get a quick release like mine. Takes 1 second to detach. You can leave it off until trail days and quickly attach it

Ok, so when all else fails, call the manufacturer. I called Firestik. One of the gentlemen told me that cb antennas are designed to reflect off of horizontal metal surfaces. On most vehicles, this is the roof, however because Wranglers don't have metal roofs it uses the tub, wheel wells, etc... He said 3' is fine and he recommended the Firefly because its more forgiving of these flat metal surfaces. So problem solved, right? Wrong! He went on to tell me that antennas (at least his brand) should not be run parallel to close metal objects because they will reflect the signal back into the antenna. Bye-bye hi-lift jack. I told him my Teraflex HD tire carrier is designed so that the hi-lift mount and cb antenna mount within 2-3" of each other. He said, "I would not recommend buying one of my antennas."

I am now thinking of just doing a bumper mount on driver's rear so its not near the hi-lift. Plus I should be able to get away with a 4'.

Pretty much so long as the top 2/3 of the antenna is clear of any metal obstructions horizontally, you will be fine. 90% of the power is transmitted out the top 3/4 of the antenna. The bottom 1/4 is the "side lobes" that react with the ground plane to make your signal travel. But since the ground plane on a Wrangler is so far below the bottom of the antenna, it's not so critical. You might lose 10% of your range.

That is the advantage of a Firestick. If you look closely at them the actual antenna mast is fiberglass that is helix wrapped by a thin wire. That wire is the actual transmitting part of the antenna. The fiberglass is just the physical support. A standard 1/4 wave antenna is 104" long. Firestick achieves this with the helix winding. Other antennas like the bottom loaded Wilson wind the first 68" of the antenna wire in the load at the base, then the actual shaft is the last 36". Those antennas have to transmit all of their power out that ending 1/3 (the shaft) and are extremely susceptible to reflecting off nearby metallic surfaces (like a high lift).

That will actually make the issue you're trying to avoid even worse. You'll be less than a couple inches from the metal body panels.

If I got a 4' then only the bottom 18" of the antenna would be parallel to the body since the top starts after that, right?

This is true.

I know someone on here has an SWR meter for tuning the antenna. That is the biggest thing you can do to get the most out of the antenna. Trying to get as close to a 1:1 SWR as possible is the aim. Most people are quite happy with anything below 2:1 but I am a perfectionist. I managed to get the one on my Willys down to 1.15:1.
