CB Radio Antenna with an Adjustable Stainless Steel Whip and Fiberglass Base for Vehicle Installations

This CB radio antenna combines a thin, flexible stainless steel whip with a fiberglass base for vehicle installations where overhanging branches or other low obstacles are a concern. Its slender profile also suits a less bulky-looking CB setup on a pickup truck, off-road vehicle, SUV or car.

The Procomm antenna has an adjustable whip and a male 3/8-inch x 24 thread that fits standard CB antenna studs and mounts. Choose a 3-foot, 4-foot or 5-foot length to suit your available clearance. For this base-loaded design, a high mounting position, ideally near roof level, is recommended for better performance. The antenna base and whip are included; coax cable, mount and stud are sold separately.
