Installing two cb antennas




















This should be done before you ever purchase an antenna. The equipment you need is dictated by where you intend to install the antenna. For example, a magnet mount, base loaded antenna is going to do you no good if you decide you want to install the antenna on your bumper.

Need help selecting the right antenna? Check out our Help Center article about Antenna Selection. Here are some tips regarding antenna location:. This process can be anywhere from very simple to very complicated. A magnetic mount just sets on the roof. A door jamb mount requires measuring and drilling and adjustments to get the antenna vertical. Follow the instructions for installing your mount as closely as possible if it came with any.

Also, make sure that you have all of the proper components to attach your antenna mount to the coax. For example, some mounts come with a stud that will require the ring terminal connector on your coax while others will require a PL connector on your coax.

Another option might be the FireRing. See an example of each here! Firestik offers some great pictures showing proper FireRing installation with regards to the antenna stud and mount. If you have ever installed stereo speakers for your vehicle, you will be familiar with this step. You want to get the cable from your CB antenna to the CB radio with as little of it showing as possible.

There are tons of tips and tricks for running cable through a vehicle online. My advice is to look for information on running speaker wire. Car stereo installers are wizards when it comes to this stuff. Here are some tips from our experience:. It will help to optimize the antenna system and ensure that you won't damage your radio. Please tune your CB antenna during installation and before transmitting with your radio.

Tune it every time you move the antenna, add a spring or quick disconnect, modify your vehicle with a large metal component, hit your antenna on something, change your coax length, switch to a different mount, and more. You can find a link to an article on CB antenna tuning here. It is essential in getting the best performance out of your setup.

Some radios have the meter built into the radio but many do not. Don't be intimidated by this process- it is fairly easy once you understand it. Here are some links to our Help Center to assist you with the tuning process:. One of our brilliant customers found a unique way to mount a 2 ft Firestik on his Honda Civic. The customer had originally purchased an MKR trunk lip mount , but didn't like the look of it.

You may need to run cable from the trunk lid through the back seat, then under the doorframe and window pillar or the dash and firewall. You have a couple of options to provide power to your CB radio: directly connecting it to the vehicle's battery or using the cigarette aux plug. Things to consider are making sure to have a fuse in the power line before the vehicle firewall and ensuring that your CB radio is turned off preferably automatically when the car isn't running.

For instance, using a cigarette plug may allow the power to be always on, quickly draining the battery. Connect the red wire directly to the positive side of the battery or to a connection on the fuse box that is always on.

Connect the black wire to the negative side of the car, usually the chassis. Any other location with good electrical contact will also work. To complete your antenna installation, you need to do a CB radio setup, and the logical first step is to use an SWR meter.

An SWR meter, whether built-in or in a separate unit, will also help you determine where to mount your antenna. If you have a separate SWR meter or other devices between your radio and antenna, you need to use a coaxial cable jumper. Your goal is to bring the SWR ratio as close to as possible, and you can move your antenna around until you locate the best spot to install it on your vehicle. Move your vehicle to a spot with no obstructions. Calibrate your meter according to the instructions, and test the SWR by pressing the key on channel 1 and then channel Note that a reading of over can damage your CB's health.

Check out our video below on tuning a number of different types of antennas. This video also illustrates what to do if your antenna is too long or too short. You can save a lot of money by installing your own CB on your motorcycle using common tools you probably already have.

You'll need an inexpensive CB antenna such as the Midland that's designed for motorcycles, as well as a place to mount it on the rear end of your bike. Also, don't forget about the in-helmet headset. The customer is using the with the mobile adapter. The mount and antenna were installed on the passenger side front fender. The customer reports, "Installing on the Hyundai Santa Fe required some bending of the bracket and even then it will result it some hood contact.

If the mount was slightly thinner this would be avoided. You could always ask a knowledgeable friend if one's available. If you don't have anyone available to you can look for additional information in our technical library. About Us. Store Links. Customer Service.

Instead of being perfectly circular, their pattern is much more oval shaped - with the oval being stretched in the direction of travel. So with a dual CB antenna setup, you'll be able to talk further up and down the direction of travel - which usually works out well given the direction of most roads.

When installing a dual CB setup, you need an absolute minimum of 5' between the two antennas. Anything closer, and the antennas will be too close to perform properly. Ideally, you should be closer to 9' as a minimum for peak performance. In addition to two antennas and mounts, you'll also need a special co-phase CB coax for wiring everything up.

Instead, make sure you get a special co-phased, RG CB coax cable. This is a special "Y" cable that has two ends going to each antenna, which come together into one end which plugs into your radio.

Again, without this special cable your dual antenna setup simply won't work. Finally, just because you're using two antennas doesn't mean you can scrimp on length. A good 5' single magnet mount antenna installed high-up on a pickup's roof will outperform a smaller 2' dual antenna setup. While you'll get the increased range up and down the direction of travel, you'll still need decently long and properly installed antennas to enjoy great performance.
