Product Overview

Southwest Antennas Part # 1085-135 is an omni-directional 4 section collinear antenna that operates over the 1.35 - 1.39 GHz frequency band. This antenna features a peak gain of 6 dBi, and has a matte black finish and a TNC(m) RF connector. The integrated sealed spring base allows the antenna to bend and flex if impacted and return to its vertical operating position, reducing risk of damage to the mated RF connector and radio.

This antenna features an integrated RF bandpass filter to help eliminate interference from other co-located radios operating outside of the antenna's 1.35 - 1.40 GHz operational frequency range, providing increased performance for attached radios.

Features: 
  • 4 Section Collinear Design
  • 1.35 - 1.39 GHz
  • Internal 3-Pole RF Bandpass Filter
  • 8W power handling
  • 6 dBi Omni Radiation Pattern
  • Rugged Construction
  • Low Glare Black Fiberglass Radome
  • Weatherproof Sealed Spring Base
  • TNC(m) RF Connector
  • End Cap Lettering “L”
