The mode of transmission changes, but the frequency does not change.Ī single sideband CB can operate on more channels than a regular CB. When you switch to single sideband, channel 19 is still 27.185MHz. For example channel 19 has a frequency of 27.185MHz. Please note that single sideband does not use different frequencies. People using a regular CB radio cannot properly receive SSB signals, it will sound garbled. In addition, some higher-end CB radios are equipped with single sideband (SSB), which is a different mode of transmission. There are a large variety of mounting options available for CB antennas.Īll CB radios operate on AM, which is the same type of transmission as a typical AM radio station. But if you choose a base-loaded antenna, make sure the package says that it is compatible with weather.īeyond that, it is just a matter of choosing a mounting method that works best for you. All center-loaded antennas and all fiberglass antennas are compatible with the weather band. If you need weather reception, make sure the antenna is compatible with the weather band.
You can find “no-ground-plane” antennas at places that sell RV and boating accessories. These vehicles need a special antenna since the body is not made of steel. This is a special antenna designed for fiberglass RVs and boats. There are always trade-offs between performance, aesthetics, and height restrictions, but just remember that the length of the antenna will have a direct affect on the range of your CB.įiberglass vehicles must use a “no-ground-plane” antenna. The longer the antenna, the better the range. There are only 3 important considerations when choosing a CB antenna: The easiest way to maximize your range is to use the longest antenna possible, and make sure that the SWR is properly adjusted. Unfortunately, these optimum conditions rarely exist and the range of your unit will typically be less depending on the conditions under which you are operating.
If we were to eliminate all negative environmental factors, a properly set up base station could communicate between 10 to 15 miles, a mobile unit 5 to 7 miles, and a hand held unit approximately 2 miles with the only variable being the type of antenna used. Certain atmospheric conditions (such as sunspot activity) can also affect the range for CBs. Tall buildings, trees, hills, and interference from other CB radios all limit the effective range of a CB radio. (For more information on setting the SWR, please refer to the relevant FAQ) The condition and location of the antenna (higher is better)The physical length of the antenna (longer is better)The proper matching of the standing wave ratio or SWR. Contributing factors include the following: There are two main factors that will affect the range of your transmissions:Īlthough the radio transmits with 4 watts of power, the performance will be affected by how efficiently the antenna radiates this power.
It's very easy to use and the integration with your smartphone helps bridge the gap between higher priced detectors with GPS.Unfortunately there is no easy answer to this question.Īll Cobra CB radios transmit using the maximum FCC allowable power output of four watts. But it's one of the most affordable options. It doesn’t have the range or the comprehensive list of features of most radar detectors. The Cobra iRAD isn't the best performing radar detector. Not once did I see or receive alerts for potential threats shared by any other drivers. And the number of detectorists that actively use a community sharing app is fewer still.

The number of drivers with radar detectors is very small compared to the number of cars on the road. The community sharing app is a great idea, but it suffers from one major flaw – it's only effective if drivers use it. Using the report button when you encounter a lidar gun or a speed trap, you create a GPS coordinate on the app and other drivers are alerted to a high-threat area when they drive near it.
