I want to use a Whip antenna with a shorter mast for clearance reasons. What performance differences can I expect from using a shorter whip antenna?
The main drawback to using an antenna with a shorter whip is that there is less area to capture and radiate a signal. As a result, the maximum distance for transmitting and receiving a signal is compromised. While the ideal length of an antenna would be 102″, for most, driving around town with that long of an antenna is asking for problems. For this reason, antenna manufacturers have specially engineered their antennas by winding the coils in a way that electrically creates that 102″ radiating element (whip), without the inconvenience of an 8 1/2” whip. Most traditional CB antennas today have a minimum total length of 2′ and a maximum of no more then 5′ or 6′. As a rule of thumb, the longer the whip of the antenna the better it will perform, with obvious differences in the various makes and styles of antennas.
