  • Engineering Drawing: All dimensions are in inches

Product Overview

Southwest Antennas Part # 1087-028 is an omni-directional antenna that covers the 2.4 - 2.7 GHz frequency band. A 2 section collinear design offers a peak gain of 4 dBi across the antenna's operating band.

This antenna features an innovative environmentally-sealed spring, giving the antenna flexibility to deflect/bend with impacts and return to its original vertical position. The integrated spring design minimizes stress placed on the antenna and radio connection, and can help prevent damage to both in the event of an impact. The spring is fully sealed to prevent rain, dust, and other debris from impacting antenna performance

The integrated 3.5" flange base with lock-wired screws allows for secure mounting of the antenna to vehicles, aircraft, or other moving platforms. The flange features four (4) .250" diameter holes for mounting.
