Product Overview

Southwest Antennas Part # 1085-220 is an omni-directional antenna featuring a 4 section collinear element design that offers 6 dBi of peak gain across the antenna's 4.4 - 5.0 GHz operating frequency range. The antenna features a weatherproof sealed spring base for operation in all weather conditions and a TNC(m) RF connector.

The antenna's integrated RF bandpass filter helps to 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.

Features: 
  • Broad Band Coverage
  • 4.4 - 5.0 GHz
  • 4 Section Collinear
  • 6 dBi Omni Radiation Pattern
  • Integrated 4-Pole RF Bandpass Filter
  • Rugged Construction
  • Low-Glare Black Radome
  • Weatherproof Sealed Spring Base
  • End Cap Lettering “C”
  • Black Chrome TNC(m) RF Connector
