The very same base and radiator design as the 42"; slightly shorter at 36" tuned specifically for the North American 2meter 144-148MHz. The copper, internal 5/8-wave antenna is encased in a fiberglass radome weatherproof and fixed cover.
Fed by RG58-A/U coax, with an FME connector for easy routing through bullbar mount holes, and vehicle firewalls or headliners.
This antenna has an exceptionally strong base spring and designed to be mounted on a sturdy mount such as a metal front bumper/bull bar. Mounting through body panels would not (necessarily) be recommended, as the moment generated by vehicle movement may bend and potentially yield body panels.
