How to Build a CB Base Antenna
Apr 14, · In this weeks video, I show how to install the CB antenna and run the coaxial cable up to the cab. This is part two of the video series on how to install a b. May 13, · Thanks for watching and I hope you learned something today on how to properly mount a Fire Stick or other CB radio antennas that require a ground plane on yo.
People in other nearby vehicles can barely make out what you are saying and incoming reception is difficult to make out. Is it the mic?
Is the antenna out of adjustment or is the CB just a cheap piece of junk. Below are some basic CB installation, setup and tuning tips. We will just keep it plain and simple and to the point. Where you install the CB itself is only important in regards to its ease of access and the orientation of the speaker so you can hear it. But overhead may not be an option and determining a mounting location is not always easy.
If you are mounting under the dash or on either side of the center console, just make sure you have enough leg clearance. There are many companies making CB mounting mounting brackets, some of which are vehicle specific for some trick installation locations.
Mic Brackets — Most sets come with a mic mounting bracket that often can be attached to the side of the CB itself. Consider your cable routing when choosing your set mounting location. You can purchase a small CB radio remote speaker that use a male mono audio w. Sometimes even a small speaker mounted in a convenient location will do. But my speaker is mounted in the dash using the old single speaker location in the CJ dash panel.
The audio quality of this setup is great. Nice and loud with a better than average speaker behind the dash. 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 ti 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 antebna 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 tl options on the market. Antsnna 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.
Pros — Popular, many options. Removable, non-permanent. Movable around on vehicle for better SWR adjustment, better reception, and avoidance of tree branches. Cons — Easily knocked off and under the wheel by low hanging tree branches. Dirt can get lodged under the magnet what is the meaning of ugly 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. What to avoid — Avoid narrow magnetic bases. Narrow ccb 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 wwire foot with a magnetic mount. Though they seem ideal for offroad use, avoid how to cut extensions to blend with short hair. They are hard to hhow 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.
Some are even designed for specific vehicles. Hood mounts, corner mounts, vehicle specific location mounts, even rollbar and roof rack mounts. Pros — Permanent, fixed location. Worry free, will not get knocked over or off the vehicle. Good grounding. Cons — Permanently mounted, may require drilling. Challenge to find a location. Hit or antebna ground plane. What to avoid — Avoid mounting the antenna too low and too close to the vehicle. The antejna common, versatile CB antennas come as ho 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. This coil can w located within the base Base-Loadedpartially up the antenna Center-Loadednear the top Top-Loadedor wound up most of the length of the antenna Continuous Loading.
Steel Whip antennas are nice because they flex well and most steel xb antennas will atnenna a base-loaded coil keeping the bulk of the hlw away from branches. Fiberglass antennas will flex somewhat but coupled antennz a spring mount, will resist damage. Atenna 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 what are portable storage devices adds additional weight or bulk to the center or top of the antenna, which is not ideal for off-road use.
All What is the job of a cna antennas shorter than a inch whip have a coil. Aire wire in the coil is the remainder of quarter ohw inches minus the height of the antenna itself wrapped up in a tight or spread out coil.
How to remove tree sap from dog fur 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.
Higher is better. Antennas can be base-loaded, center-loaded, top-loaded or continuous-loaded. How do you identify what type of antenna is what? Base-Loaded — How to wire a cb antenna 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 wlre.
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.
Top loaded CBs are usually fiberglass construction with a thin wire wrapped around the fiberglass pole and covered in a protective layer of vinyl plastic.
The thin wire is wrapped tighter wirre the top placing most of the wire near the top. Benefits wide a top-loaded fiberglass antenna is that option to mount the antenna lower on the vehicle yet placing anntenna of the antenna higher, hopefully above the roofline of the vehicle.
Continuous-Loaded — Continuous loaded antennas are very similar to top-loaded antennas in their construction with the exception of the wire distribution over the shaft. With continuously loaded antennas, the wire is not concentrated towards the top or bottom, but rather distributed evenly over the aire length of the shaft.
There is very little benefit to continuous loading vs top loading. When installing wir CB, you have a long coaxial cable that runs from the CB to the antenna. Typically this is about 18 foot of cable, which according to some theory, is the optimal length of cable to use regardless of how close the antenna is to the CB.
So if you how to wire a cb antenna 18 foot, you probably have some or a lot of extra cable to deal with. This will cause performance issues. Instead spread out the wire loosely in ajtenna lengths.
Route the cable out of the way as good as possible. If the antenna wier in the rear tto the vehicle, that can be a challenge. Under carpet, along the door jam, under the seats, along the roll cage are all common ways to route it.
This can result in a damaged CB. CB Radio Articles Installations […]. Equipment needed: SWR meter, short jumper coax 3 foot. Connect the antenna normally connected to the back of the […]. With each condition several anyenna causes are listed along with possible solutions to get […]. I am looking for a video on how to install mount CB radio into the ceiling of Toyota Tacoma truck or any kind of truck. Anybody got any HELP?
I do not want to leave the CB in my car all the time. I just want a plug and wirr install. If I tune this thing does it matter if I remove it and return it to the set up in the morning? As long as you do not change the coaxial cable length and do not disturb how you routed the coaxial cable, your SWR should remain the same.
If you adjust your SWR to optimal and later want to remove the radio, you may want to remove the antenna too. If you remove the antenna make sure you put it back in the same place you had it and route the wire exactly like you had it or the SWR may change from the original setting.
Step-by-Step Instructions: Grounding a CB Antenna
Dec 11, · Step 1: Hardware. -CB radio (Mic included) -Antenna (may already have Coax cable) -Coax cable (may already be connected to the Mount/Magnetic Mount) -Tapping clips (1) -Antenna spring (so it'll flex in lieu of snapping/shattering) Note: All CB radios are equally powered (out of the box), but not always the same price. Dec 14, · Assembling your CB Base Antenna. Place the 1 inch EMT connector through the center hole of your round electrical box. This will require you to make the initial hole larger. When putting this in, put it in in the reverse manner that you normally would. Put the 4 1/2 inch connectors through the 4 holes in the sides of the box. Running the wire from the Antenna to the CB. When installing a CB, you have a long coaxial cable that runs from the CB to the antenna. Typically this is about 18 foot of cable, which according to some theory, is the optimal length of cable to use regardless of how close the antenna is to the CB.
Are you having trouble with your CB transmissions? Is your radio losing signal on your car too often? Then you might need to invest in a new antenna for your CB radio. It's important to have an antenna for a strong signal on your radio. You can make your very own CB antenna , right from the comforts of your home.
How, you ask? In this article, we are going to tell you all the things you need and all the steps that go into making a CB antenna. With just a few materials and tools at hand, you'll be the owner of a brand new antenna for your CB radio. And that too, without a trip to the store. A homemade CB antenna will work just like any store-bought antenna. You can adjust the height according to your needs and have control over it from anywhere in your vehicle.
The antenna will work best if you can customize it according to your needs and the type of vehicle you'll be putting it in. Even the best CB radio on the market works with a power of 4 watts. With this power, you'll be able to send and receive from a few miles at most. If you want to improve the signal strength, you have to increase the distance over which you are sending and receiving messages.
You'll have to keep in mind things like the height of the antenna, as well as where and how it's mounted on your car. In case you can mount your CB antenna in the right place, you can get up to miles. A sweet deal compared to the miles you're currently getting.
Before you can make an antenna, you must understand how it works. CB radios use a frequency band of 27 Mhz. And the wavelength of this band is a little over 17 feet or inches. What you'll need to do is take two halves of this wavelength, that is, two inches of copper wire.
Then you have to insulate and ground these two lengths of wires, connect them to your CB radio, and finally mount them to the highest point of your vehicle.
Below, we have made a list of all the materials, tools, and instructions that you need for your homemade CB radio. This could be made of wood, aluminum, or PVC. Whichever you choose, make sure that it's sturdy enough to withstand a strong breeze. We recommend you to use a quarter-inch fiberglass pole but really, any of them will work just fine.
For proper transmission. Note that you actually need inches to match the wavelength, and the extra 8 inches will be used to attach the copper wire. To connect the antenna with your CB radio, you need this cable, so it has to be long enough to stretch from where your antenna will be mounted, to the place in the car where your radio is. Step One: Take the insulator eggs and wrap 4 inches of each end of the two copper wires around the hoops of the insulator eggs. You have to make sure that there are no pointy ends and that they have a strong mechanical and electrical contact twist at the ends.
Then, solder the twists together. Step Two: Cover the antenna rod with the double sided tape all the way from top to bottom. Step Three : Start wrapping the two copper wires around the rod. Make sure the wires don't touch each other. The wires will go up parallely, and once you're done, it'll look as if you've wrapped four wires around your rod.
Step Four : Cover the entire rod using the duct tape. You can wrap it spirally or lengthwise, whichever is easier for you, but make sure that the whole rod is covered except for four or five inches for the mount. Step Five: Cut off one end of the RG-8 cable and using your soldering iron, solder the center lead wire of the cable to one end of the insulator egg.
This is your transmission connection. Step Six : Take the silver braided part of the RG-8 coaxial cable and solder it with the other end of the insulator egg. This is your ground. That's it! Now that you've made your antenna, it's crucial that you mount it somewhere on the car where you'll get a maximum signal. Antennas can be mounted on various places, for example, the roof, trunk, bumper, hood or even mirror bars.
You're likely to get the best signal in your car if you can mount it in the middle of your vehicle. Although tuning is not exactly a part of making the physical antenna , without tuning your antenna, you're not going to get a good signal on your radio. You'll be able to get better tuning results in open spaces. Use an SWR meter to get the two readings as close as possible. That's how simple making your own homemade antenna is. Most of the materials are readily available in hardware stores, and a couple of hours of your time will give a huge boost on your CB radio.
