When Should a No Ground Plane CB Radio Antenna Be Used on a Vehicle?
The most common form of CB radio antenna is known as a top-loaded antenna. These types of antennas use the metal chassis of vehicles to help ground the antenna whilst transmitting radio frequencies. This type of antenna is popular because there are very few restrictions associated with mounting it on your vehicle. One benefit of top-loaded antennas is having the coil near the top, allowing it to be placed anywhere on your vehicle and still providing a great reception. But what do you do if your vehicle does not have a metal chassis? This is a common problem when trying to use a CB on a RV, boat or other vehicle without a metal chassis. Trying to mount an antenna on one of these types of vessels requires you to use a No Ground Plane antenna. Unlike a traditional top-loaded antenna, a no ground plane has the required ground counterpoise built in to the coax cable and does not need the assistance of a metal chassis to transmit the radios signal. However, since a traditional ground plane a
