Automobile Antennas

The Comtech ADM series high efficiency mobile antennas are designed to be used on vehicles equipped with VHF/UHF radios.

Each antenna is either a fixed mount version or supplied with magnetic mount and 5m length coax cable terminated with PL-259 Type Male, BNC or Mini-UHF Type connector at your choice. The connector may be not installed and supplied as a part.

Each antenna is designed for high endurance applications and completely protected from corrosive gases, ultraviolet radiation, salt spray, acid rain and abrasives such as windblown sand in desert environments.
