Product Overview

Southwest Antennas Part # 1085-135 is a 4 section collinear omni antenna with a frequency range of 1.35 to 1.39 GHz and 6 dBi of peak gain. This product features an integrated RF bandpass filter to help eliminate interference from other co-located radios operating outside of the antenna's 1.35 - 1.39 GHz operational frequency range, providing increased performance for attached radios.

A matte black radome and black-chrome RP-TNC(m) RF connector offer a low visibility finish that will not attract attention when deployed. The waterproof sealed spring base allows the antenna to bend or flex with impact and return to its vertical operating position, reducing risk of damage to the antenna or mated radio RF connector.
