Product Overview

Southwest Antennas Part # 1032-046 is an omni-directional bifilar antenna with an operational frequency range of 405 - 460 MHz and 860 - 935 MHz. This antenna's unique dual-polarized design allows for reception on both the low and high band without interference between the two bands.

The antenna's bifilar architecture provides a number of benefits, including complete overhead radiation pattern cover over the antenna, eliminating the keyhole null that is present with many omni-directional antennas. The circularly polarized design is ideal for communication with overhead aircraft, UAVs, or for C-UAS product solutions.

Integrated bandpass filters for both bands help to eliminate interference from other co-located radios operating outside of the antenna's operational frequency ranges, providing increased performance for attached radio systems.

Features: 
  • Dual-band bifilar antenna:
    • 405 - 460 MHz (LHCP)
    • 860 - 935 MHz (RHCP)
  • Cross polarized design
  • 1.2 dBic gain
  • Integrated bandpass filters for both low and high bands
  • Rugged G10 fiberglass radome
  • Spring base for RF connector strain relief
  • Type-N(m) RF connector

Note: This antenna is for receive-only applications and includes an integrated RF limiter. The limiter has a maximum input power of 1.5W, and it compresses input signals between +5 dBm and +30 dBm down to 0 dBm.

Applications:

  • Tactical radio systems
  • Air-to-ground communication systems
  • Ground Control Stations
  • Counter-UAS (C-UAS) / anti-drone systems
  • Mobile radio systems and vehicle applications
  • Fixed site infrastructure
