Best CB Base Antennas [2021] My 7 Favorite!

Installing an antenna close to your home or on your car is the best way to stay connected to the world, especially during an emergency scenario where the landline is shut down and you can’t call anyone for help. 

While this might not necessarily be a bad thing by any means, it does make it quite difficult for people who are new to antennas to know what product to pick.

Here is where I come in.

The most popular antenna models are center-loaded, whip, magnet mount and fiberglass. If you have trouble looking for the right product for your needs, then you need to consider where you are going to install it.

You can position it in multiple places but as a rule of thumb, you should always look to mount it in places that are higher to help signal.

We are going to kick things off with the antenna sold by Sirio which is a renowned manufacturer in the industry.

This antenna model offers omnidirectional high power handling and it features a low radiation angle. 

What makes this model stand out is the fact that it is equipped with multi-element ground plane protection from static discharges “DC-ground” that is made from aluminum alloy (6063 T-832).

If the power of the Sirio antenna wasn’t enough to get you onboard, then you should know that it features a 5/8 ground plane frequency range that can be tuned from 26.4 to 28.2 MHz.  Furthermore, this model features a max power of 1,000 Watts (CW) and continuous 3,000 Watts (CW).  

The coil that is equipped on installed on the Sirio antenna is made of enameled copper wire of big section which has been specially designed to support high powers.

Another interesting feature that we want to highlight is that this antenna supports the exclusive System C.A.C.S which stands for (coil auto-cooling system).

This is an outstanding system that allows the auto-cooling of the antenna to run by finned support which keeps coil hanging up allowing for smooth air circulation. 

Last but not least, the antenna from Sirio is manufactured in Italy with high-quality materials such as telescopic fiberglass tubes for example.

Best CB Base Antennas - Frequently Asked Questions:

#1 How high should a CB radio's base antenna be?

Right from the start, we want to mention that the antenna’s height is the most important factor in how effective its power can be. This factor is so important a poor antenna will always work better than a heavy-duty one if it's based at a higher location.

The reason behind this is that all communications at CB radio frequencies require a “line of sight” and even though radio waves have the power to penetrate walls, their power is sometimes limited if the antenna is placed in a bad position.

We are not going to present how the technology behind CB radio base antennas works and instead, we are going to directly give you the answer that you are looking for. In the United States, the FCC rules are stating the antenna is legal if it complies with the following rules:

  • The antenna is no more than 60 feet above the ground;
  • The antenna is no more than 20 feet above the top of the tree or building to which it is mounted.

#2 Are dual CB radio antennas better?

Do you use a single antenna and it doesn’t feel powerful enough for you? If that is the case, then you should be pleased to know that using dual antennas is going to double their power! This setup is mostly seen on big rigs and the antennas are mounted on either side of the truck. The positioning is making sure that most of the signal doesn’t radiate out from the passenger side while still doubling the power of the antenna.

What you will want to do in order to achieve the best radiating pattern dual antennas is to place them ½ wave apart from each other when installing. This is around 204 inches apart. We also want to mention that dual antennas can also be mounted close to the vehicle body and they won’t cause any unwanted signal reflection.

#3 Can you use a mobile CB radio antenna for base station antenna?

Yes, you can use a mobile CB antenna for base station antenna. However, there are a couple of important tips that you need to follow in order to make this possible. First, you are required to connect the power source wires of the CB radio to a power supply. This is required because CB radios are designed to run in vehicles and they require a power supply of 12/14 volts Direct Current (DC). You can attach the wires of the CB radio to the power supply by simply stripping the ends of the wire and wrapping them.

The second step is to attach an antenna to the CB radio. A useful tip here is that mobile antennas usually have mounting brackets that can clamp to the rain gutter of the car. Fortunately, you can simply straighten the brackets and use them to mount the antenna to the house walls.

#4 What is a good CB antenna?

It’s difficult to determine what makes a good antenna because above everything else, it needs to fit your needs. This is why we are going to present you the two types of antennas so that you know which one to pick. First, there are fiberglass antennas which are the cheapest models. They don’t always offer the best performances, but they are reliable.

We also have the whip antennas that can be either center or base loaded. What makes them stand out is the fact that they have a long steel whip and they need to be mounted high on a vehicle. To offer better coverage.

#5 Does a magnetic CB antenna need to be grounded?

Even though you have purchased the most expensive antenna, you will not receive outstanding performances if you don’t install it right. This is why one of the first things that you need to do after buying a new antenna is to ground the mount.

The mount on standard antennas needs to be grounded to the vehicle’s frame. Placing the mount on a bad ground will result in an un-table antenna and more importantly, sky-high SWR levels.
