I'm going to assume you've got a PL-259 connector on the end of the coax cable - they look like this:

They are designed to screw onto the radio's RF / Antenna jack. The end shown is standard, the other end - that the cable enters, requires an insert that matches the coaxial cable outside diameter.

There are two versions of the connector; solder-less and soldered. The best connection is provided by the soldered type. It is superior both electrically and mechanically to to the solder-less version. If you lack soldering skills, patience and / or the tools and supplies to solder the connector, the solder-less version will be the way to go.

There are two types of solder-less types, a crimp and non-crimp type. They look like these:

The "Non-crimp" solderless PL-259 from
A crimp type PL-259 connector - $2 and up at various radio & electronics stores.

Since this end of the antenna is at the radio and presumable protected from the elements, it may prove to work very well for you. Each of these connectors requires knowing the type cable (RG-58 and RG-8 are very popular types - but there are many other 50 ohm coax cables) or outside diameter and selecting the one that fits correctly, along with a crimping tool (and dies) for this particular connector size. You may get by with a standard pair of pliers, but the connection is not as good as would be obtained with the crimp tool. Generally, you would provide a crimp around the ferrule at the cable end for the braided conductor and another at the very tip of the connector for center conductor.

Each connector will include very specific cable preparation steps for the removal of insulating jacket, braid and dielectric material to provide proper fit of the connector to the cable. If it were a "standard", I would have included it.

I hope this helps & good luck!

A couple of suggestions:
1. verify that the RF Gain is maximum clockwise;
2. verify that the ANL or noise limiter is OFF;
3. pls add a ground strap from the body of the Cobra 29LTD to the chassis/GND of the vehicle or to your house GND connection;
4. Verify that your Wilson 5000 has a sufficient ground plane such as roof or metal objects.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

SOURCE: Procedures to install cb antennae mount

The end without a connector was once attached to an antenna. You need a proper antenna in order to use the radio. If you were to buy a new antenna, it will come with a length of cable attached. Even if you were to buy a new antenna, don't expect good performance from the radio unless you get the antenna properly adjusted. Yes, it will work "out of the box", but probably not as good as it could. There is a device called an SWR bridge, it's used to measure the SWR and the user then adjusts the antenna for the lowest reading by trial and error adjustment of the antenna.

Hi and welcome to FixYa,

Initially, determine if the needle will deflect signifying power output when switch to PWR:

  • if yes, then check continuity of coaxial cable as well as grounding of antenna mounts;
  • if no, then the finals and driver would require further looking into (8 X IRF520).
Additionally, check the 2 30Amps fuses

Good luck and thank you for asking FixYa.

As for me ,the Wilson 1000 or Wilson 2000 are the best mobile antenna for a mobile. I have out talked a lot of base antennas with them, just put it on the top of car in the center or trunk, or middle of cab of truck, with a good SWR and you are talking and receiving. great antenna. ...hope this helps..

Measure out your coax in 3ft intervals. Like if you need 7ft use a 9ft length of coax. Also make sure your mirrors are grounded use a external swr meter as well, the internal swr on the galaxy could be off. .

I am having a problem with mt cb. I used all new coax, antenna, antenna stud and mount. New mic and radio. The problem is I hook up the swr meter, keyed and the meter swung hard right. I have changed

ok, you have a high SWR.. this is what you can do.. you're gonna need to check the Radio's coax connection to see if it's loose on the Radio itself.. you're gonna have to open the Radio cover on the speaker side.. now go look at the connections on the pc board itself and see if there is a possible broke connection.. one is pcb ground, and one for the center. also, you might want to get a phillips head screw driver and gently tighten all the screws on the pc board. becareful going in there.. after this said and done, check the antenna connector itself to see if it's loose. if so, then you're gonna have to a pair of pliers to turn the nut on the inside while you use wrench to hold it in place on the outside.. now you're ready to test the radio.. don't put the cover on just yet until you see the results. set up your SWR Meter to the Radio and then set up the dummy load and do a SWR Test. if the reading is good, then the Radio is all set.. now for the Antenna.. you said that it's all new, but regardless you need to test it too.. check both ends of the cable and do a condinuity test.. get a ohm meter that has an audio sound. this will help you.. set the meter to ohms/conditnuity.. then short out the probes to get a ZERO reading/audio sound.. now take one end of the of the cable and put the probes on the connector.. one probe for the outter ground shell and the other probe to the center pin connection. if you see a ZERO reading or an audio sound, that means you have a short in the cable.. another way is to do it end to end.. put one probe on one end of the cable, and the other probe on the other end.. test the ground side first.. if you get a sound or a ZERO reading, that means you may have a short in the cable itself and may requier to remove the connectors.. some cases you might have to replace them.. remember to calibrate your meter when testing let me know how it goes.. I'll continue to help you.. you can contact me on Facebook.. Good Luck..

I have a wilson 5000 mirror mount. I mount it on the drivers side mirror on the upper cross arm that goes to the mirror. It is mounted on this arm with a bracket and a so 239 connector so I can undo it if I have to ,leaving the antenna connected.I can change coax and not have to worry about undoing the antenna. Remember one thing. The antenna has to be checked for SWR.each time you move it to a different spot or to a different truck.

Having trouble setting swr .moved anttena up and down 1/4 inch at a time and there is no change

There are several things that can cause you not to be able to get an acceptable SWR.

The first is the most obvious. Poor antenna, or bad coax. Make sure your coax is good. Make sure the antenna is mounted in a good location.

Some things I have seen that cause this problem.

  • Wilson Little wil, almost impossible to get under a 1.6 SWR.
  • Fiberglass antenna's, a break in the wire near the top of the antenna. Will show the antenna as being too short, and adjusting the top will do nothing. This antenna is no good.
  • Common mode current. This is when the RF is traveling back down the outside of the coax, and or causes the coax to act like part of the antenna. SOLUTION. As close to the antenna as you can, take 6 to 8 inches of coax, and coil it into a tight coil, about the diameter of a spray paint can. In fact using a spray can to wrap the coax around works well. Use electrical tape to secure the coil so that it will stay tight and uniform. This will stop common mode.
  • missing foil/vinyl membrane on bottom of magmount antenna. This is essential for the antenna to see ground plane.
  • bad connections on coax connector.
  • Cracked isolator on stud mount.
  • incorrect procedure for taking SWR reading.
  • Poor location of antenna. E.g. antenna's load not above roof of vehicle.
  • Incorrect length whip being used.
  • corrosion of any part of the antenna system.
There are some cheap antenna's out there that you just can't get lower then say a 1.5 or worse, like the wilson little wil. Wilson makes great antenna's. The 500, 1000 and 5000, as well as their silver load antenna's are excellent. I have been able to get them all to at least a 1.1 SWR, and some like the 5000, and silver load fiberglass whip to 1.0 using an analyzer. The Little will is just a poor antenna. Anything under 2.0 SWR is okay of a barefoot radio, although I don't like going over 1.5 my self. A barefoot radio, will do a 2 swr all day. If the radio is stock, and not peaked and tuned, 2 swr is fine and won't hurt the radio.

You should always try to get the lowest SWR that you can in any case. The lower the SWR, the more RF energy is leaving the antenna. As well, receive will improve the closer you get to a perfect match. This is known as being "On Que".

Check everything I have listed that applies. And if nothing fixes it, you may want to try a different antenna. Some antenna's just don't work well on certain vehicles.

How do i install a cb radio on a pick up truck

You will need a CB radio antenna, The CB radio and mounting hardware as well as the power wire.

Choose a place to mount the radio. Mount it. Run the power wires from the radio to the fuse box. Put red wire in with the fuse that is hooked to switched 12 volt. Ground the black wire to any metal of the vehicle.

Next find a place to mount the antenna. If you use a mag mount, the roof of the cab is a best bet. Run the wire into the vehicle, it can go through the door, just make sure its not going to get pinched.

Hook the coax from the antenna to the radio

Now you have to tune the antenna. this is important because if you don't you you will blow the transmit final transistor out in the radio.

This link will take you to an article that will explain how to tune your antenna.

Setting SWR

hi ken, SWR has nothing to do with your power supply, Standing wave ratio, It is the amount of power which is reflected back to the radio when transmitting, If you have a SWR of 10 or over on a wilson 5000 I would imagine you have a short in your feed line[coax].
I would replace the pl259 connector and check the coax for damage.

I have a 03 f 250 superduty v 10 i would like to know how to know where to drill hole in roof and how to run coax wire to cb

all vehicles normally have spot at the dome lights. to put cb/ham/commercial antennas. but some ford trucks have a center rib on the roof which sometimes would have to off-center an antenna. on newer trucks. I would use the ham NMO mount that has the 3/8" hole (not3/4") and use a wilson 1000-5000. or tram base load antenna.. depending on power wattage needed. we normally carry the 3/8" mounts they have coax and pl259 connector on them. look us up. lowest prices guaranteed.
