Correctly Install a CB Radio

You will find very short stubby CB antennas no taller than a foot with a magnetic mount. When installing a CB, you have a long coaxial cable that runs from the CB to the antenna. On most modern vehicles the 12V acc plug cig lighter wiring is not enough to handle the amperage of a CB radio wile transmitting.

Not something we will get into here but we will say, keep the inline fuse in place and DO NOT hook up the polarity backwards! Center-Loaded — Center loaded antennas usually have the coil further up the antenna but not always in the center. Narrow means easily toppled over. Avoid stiff antennas with a magnetic base. Cheap Tricks and Useful Tips.

For now, these are just instructions on How To Correctly Install what you've got. Mount in a place where you can clearly see what channel you're on, and you can comfortably reach the unit. From the driver seat tho this picture was taken from the passenger's POV , this spot is ideal for me. And mount the spring onto the magnet mount. Connect the ground wire to anything metal -if you have one. My Tri-Mag antenna mount is already prewired with a Coax cable. After connecting the antenna to the Spring, and the spring onto the mount, I just put the mount where the signal wouldn't be blocked or interrupted.

The Coax should be routed from the antenna to the radio with as little 'kinks' as possible. Now it's time to connect to the power supply! Remove any necessary panels to get to the back of your lighter plug. This clip makes a clean connection with the radio and the 12V DC line. Now, find any metal screw attached to your car's metal body panel, and crimp the end of the BLACK- wire onto that bolt.

Your radio is now ready to go! However, keep in mind that if you use the cigarette lighter to power other devices, it may overload the current and blow the fuse.

Use the recommended fuse rating for your set. Do not use a fuse over the recommended rating. You are not doing your CB radio any favors by increasing the size of the fuse, your only asking for damage.

Your CB will run just fine off of the power from the 12v power supply plug but if you are mounting the CB permanently, you might want to consider wiring the CB into the accessory wiring harness.

Not something we will get into here but we will say, keep the inline fuse in place and DO NOT hook up the polarity backwards! Hooking up the power backwards will probably burn out the protection diodes immediately.

Red is positive 12 volts and black is ground. There are a myriad of CB antenna mounting options on the market. With Offroad in mind, there are good choices and bad choices in antennas and mounting options. Lets start with the antenna mounts. A magnetic mount uses a large flat magnetic base to secure the antenna to a steel panel on the vehicle. Cons — Easily knocked off and under the wheel by low hanging tree branches. Dirt can get lodged under the magnet and scratch the paint.

Most magnetic mounts are base loaded, meaning most of the coiled antenna wire is low at the bottom, which in most cases means reception and output is less than what it could be. Only sticks to ferrous metal steel hoods, not fiberglass Jeep tops.

Sometimes hard to ground. Narrow means easily toppled over. Wide and flat is better. Avoid stiff antennas with a magnetic base. Stiff will not flex easily on contact and will get knocked over. You will find very short stubby CB antennas no taller than a foot with a magnetic mount. Though they seem ideal for offroad use, avoid them. They are hard to adjust the SWR and get terrible range. Bolt on brackets include a wide variety of bolt-on antenna mounts that come in all kinds of custom designs for various locations on the vehicle.

Hood mounts, corner mounts, vehicle specific location mounts, even rollbar and roof rack mounts. Worry free, will not get knocked over or off the vehicle. Cons — Permanently mounted, may require drilling. Challenge to find a location. The most common, versatile CB antennas come as steel whips and fiberglass tube antennas of various heights. Most common antennas use the quarter wave length about 9 feet with most of the antenna wound up as a coil. Steel Whip antennas are nice because they flex well and most steel whip antennas will have a base-loaded coil keeping the bulk of the antenna away from branches.

Fiberglass antennas will flex somewhat but coupled with a spring mount, will resist damage. Some fiberglass antennas have the benefit of being center-loaded and top-loaded putting most of the antenna as high as possible for better output and reception. Though not unbreakable, fiberglass is strong and light-weight. Center-loading or top-loading a steel antenna adds additional weight or bulk to the center or top of the antenna, which is not ideal for off-road use.

All CB antennas shorter than a inch whip have a coil. The wire in the coil is the remainder of quarter wave inches minus the height of the antenna itself wrapped up in a tight or spread out coil. The location of the coil affects output because the higher the coil is on the antenna, the higher the bulk of the antenna is in relation to the ground and the vehicle.

Antennas can be base-loaded, center-loaded, top-loaded or continuous-loaded. How do you identify what type of antenna is what? Base-Loaded — Base loaded antennas have the bulk of the antenna at the bottom of the antenna within a sealed plastic base, usually attached to the magnet or secured to the roof of the vehicle. Most magnetic mount antennas are base loaded due the weight and bulk of the coil.

Center-Loaded — Center loaded antennas usually have the coil further up the antenna but not always in the center. Center loaded antennas will generally have a thicker steel shaft up to the coil for support. Top-Loaded — Top loaded antennas are very common and inexpensive yet are also the most efficient.

If you connect directly to the battery, be sure to turn your CB off when you exit your vehicle so you don't end up with a dead battery.

Below are some basic CB installation, setup and tuning tips. Route the cable out of the way as good as possible. They are hard to adjust the SWR and get terrible range. The majority of CB cobra cb hook up have two wires, a positive wire red and a negative wire black. Mic Cobra cb hook up — Most sets come with a mic mounting bracket that often can be attached to the side of the Xb itself. Now it's time dating sites wales connect to the power supply!
