Product Overview

Southwest Antennas Part # 1085-131 is a full wave dipole Omni antenna that operates in the 1.35 GHz - 1.39 GHz frequency band and features 4 dBI of gain. Overall antenna length is 12.47 inches, with an outside diameter of 0.812 inches. This antenna is ideal for military or law enforcement applications, and can be paired with multi-antenna MIMO / MANET radio systems or used in single antenna system configurations.

The Ultra-Flex spring is fully sealed to prevent rain, dust, and other debris from impacting antenna performance, which is also fully submersible once securely mated to a radio. The Ultra-Flex spring gives the antenna flexibility to deflect/bend with impacts and return to its original vertical position, minimizing stress placed on the antenna and radio connection, and can help prevent damage to both in the event of an impact. A G10 fiberglass radome holds up to abuse in the field, and a low-glare black finish and black chrome TNC(m) RF connector helps the antenna blend into surroundings and not draw attention.
