Product Overview

Southwest Antennas Part# 1000-050 is a rugged monopole antenna with an operational frequency range of 225 - 450 MHz. Internal matching components within the antenna allow it to deliver a wide operational bandwidth while matching the antenna to 50 Ohm systems. An integrated highpass filter provides >44 dB of isolation in the 30 - 90 MHz band.

Features: 
  • 225 - 450 MHz
  • Monopole Design with built-in 50 Ohm matching network
  • 0 dBi Gain
  • Integrated highpass filter
    • >44 dB of isolation in the 30 - 90 MHz band
  • Lightweight design
  • Bandwidth achieved by using internal matching components (within antenna)
  • Extremely rugged design
  • Low visibility / reflectivity
  • Highly flexible
  • Waterproof & fully potted design
  • Black chrome non-rotating TNC(m) RF connector
  • 20 Meter waterproof design (when fully mated)

Note 1: The specifications and performance of this antenna are dependent on antenna matching network and counterpoise dimensions, and may be affected by other antennas on the radio.

Note 2: 50 Ohm impedance is measured at the antenna connector when mounted to radio counterpoise.
