Product Overview

Southwest Antennas Part # 1085-240 is a dual band omni-directional antenna designed to operate in the 414 - 460 MHz and 895 - 935 MHz UHF frequency bands. The half wave dipole design offers a peak gain of 1.6 dBi.

This antenna is ideal for multi-band tactical radio systems, allowing operators to utilize one or both frequency bands without needing to switch out antennas.

This antenna features a rugged matte black fiberglass radome, sealed spring base, and black chrome RF connector. The sealed spring base allows the antenna to be used in all weather conditions without concern for the spring fouling due to exposure to rain, dirt, or mud. The sealed spring also provides strain relief for the mated RF connector.

Features: 
  • Dual Band Coverage:
    • 414 - 460 MHz (1.2 dBi peak gain)
    • 895 - 935 MHz (1.6 dBi peak gain)
  • Half Wave Dipole Antenna Design
  • Omni-Directional Antenna
  • 50 Watt RF Power Handling
  • Rugged Black Fiberglass Radome
  • Environmentally Sealed Spring Base
  • Rotating Black Chrome TNC(m) RF Connector
