Product Overview

Southwest Antennas Part # 1085-146 is a 4 section collinear dipole omni antenna with a frequency range of 4.4 - 5.0 GHz and 6 dBi of peak gain. Part # 1085-146 features a black chrome SMA(m) RF connector and weatherproof sealed spring base.

This product features an integrated RF bandpass filter to help eliminate interference from other co-located radios operating outside of the antenna's 4.4 - 5.0 GHz operational frequency range, providing increased performance for attached radios.

The flexible spring base is fully sealed to prevent rain, dust, mud, and other debris from impacting antenna performance and fouling the spring, and gives the antenna flexibility to deflect/bend with impacts and return to its original vertical position. This can minimize stress placed on the antenna and radio connection, and can help prevent damage to both in the event of an impact.
