AD-55/A: Ultra Wideband Manpack Antenna with spring - 400 - 2800 MHz

The antenna AD-55/A is the ultra-wideband manpack antenna intended for use with modern broadband software-defined radios (SDR) and other radio devices (jammers, scanners, etc.). The antenna is a sleeve dipole center fed design thus enable to work without the presence of the ground plane. The radiation part of the antenna is fully enclosed in a fiberglass radome. The antenna is also equipped with the spring element allowing the antenna to be always in a vertical position. The antenna construction is rugged and intended for use in the harshest military environments. The antenna connector is N male.
