I have a cb radio that a friend gave me and I was wondering what all I needed to hook it up as far as antenna and all that

No, that is a separate purchase. You will need an 18' coax if you plan on mounting it in the back.

^ depends what you buy really. Some antenna's come w/the cable. Especially the older ones. As well, your antenna size will determine your range capabilities. On the trails, I don't even have my antenna outside the Jeep. Its in the back, tied along my rollbar just inside the cab. Plenty of range to keep w/the group for sure.

Really depends a lot on what your using it for. Tight groups, you don't need a lot. Travelling and talking to truckers all day while on the road? You might want a large antenna and maybe even a signal booster as an example.

Depending how much you want to spend, check around to resale shops, salvation army, etc... I got my Cobra radio without an antenna for $20 then I used an antenna I had in the garage from another radio that died years ago...

Nope. The coax wont attach to the antenna, you are gonna need a stud, like a firestik k4a. It will need a mount to hold it (and the antenna). You need those in addition to said antenna, coax, and radio. Make sure the coax is the right type of connector for the stud.

My jeep already has a mount for the antenna ok thanks for the help just need to figure out where to mount it now

Being a HAM operator and very familiar with antenna theory and design I want to interject that the size/length if antennas are fractions of the wave length with CB frequency being about 11 meters. That said, another thing is while having the antenna inside the vehicle may work two things it also does. One, it causes your radio to work harder and heat up faster because the signal actually has difficulty with metal and glass. Second, related to the first a great antenna inside your vehicle will work less than a crappy antenna outside your vehicle because of the already mentioned limitations caused by the vehicle structure. Having said that, few vehicles are more ideal than a Jeep when it comes to using an antenna inside the vehicle due to the fact that the Jeep (Wrangler) tends to have less metal and glass above the body. I hope this helps some on this topic. Also, another thing that is helpful is having a decent metal surface at the base of the antenna. That helps with the transmission kind of like a mirror reflecting light. If you mount it on some place like the top of a fiber glass consider ground planes (steel rods) to help with that.

Welcome to the forum. I'm on 146.52 in my Jeep.

Just to clarify as most on here aren't well read in the subject (cause its boring or so she tells me, lol), some antennas subscribe to that, like the 108" whip. (108"x4=432", 432"/12=36', 11M=36.089...ft.), but most jeepers won't run a 108 off road cause its mean to whip your friends spotting you. Also, many off road parks and groups have banned them for wheeling.

Anything shorter than the 9 foot whip on 11M is not 1/4 wave in height, but can be 1/4 wave.

The commonly used fiberglass firestik and wilson 3 or 4 ft antennas have a different physical and electrical length, with the electrical antenna wrapped into a coil around the inner shaft of the physical antenna, providing a shorter physical height. This allows whatever length you wanted, with 1/4, 1/2, & 5/8 being the most effective (depending on band/install type/location).

Then others still have visible coils or windings in them like a crazy straw, though not typically for HF, usually only UHF and above.

After rereading the thread, let me add that fwiw "signal boosters" are against FCC regulations, use of them is a federal crime. You will likely never get in trouble, BUT;
A marina in Redondo Beach is being fined several thousand dollars for putting a wireless camera on a palm tree in their parking lot. It broadcast the signal to the receiver on a FAA freq. so they got nailed - very quickly by local FCC officials with locating devices (trinagulate the signal and all that jazz)
A man in FL got a 20k$ fine for operating w/o a license, he didnt pay and it has been turned over to the Justice Dept for prosecution.

When they get mad, they get even. All 11M (citizen band) is restricted to 4w peak output, meaning you put out 3ish if not adjusted or tuned.
They are also pointless. Why holler louder if you cant HEAR better? Go HAM if cb doesnt reach far enough.

Back to OP, for outside mounts the hood cowl is best antenna wise, then front bumper, then rear tire mount / tail light / bumper, in that order. Higher is better. Metal underneath is better. Swr under 2 and the range you want for what your doing is all ya need.

Fractions are essentially indefinite in number so it's true a 11m antenna isn't feasible much less helpful. But utilizing different shapes you can certainly get it to a reasonable size. My point was going with bigger isn't the answer. Something that resonates the right frequency is the most important thing along with good grounding is. While most HAMs will say CB is somehow deficient the fact is for open spaces CB is perfect even with the power restrictions. But the antenna is the key to success.
