Omni Broadband Whip Antenna, 225 - 512 MHz, 2 dBi, Type-N(m)
  • Elevation Pattern: Referenced to +5 dBi
  • Engineering Drawing: All dimensions are in inches

Product Overview

Southwest Antennas Part # 1000-040 is an omni-directional monopole antenna, designed for operation across the 225 - 512 MHz frequency band. The antenna features a flexible whip, with a fully potted and waterproof base that contains the antenna's matching components. This rugged design allows the antenna to be deployed in harsh operating environments.

Features: 
  • 225 - 512 MHz
  • Monopole Design with built in 50 Ohm matching network
  • 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 Type-N(m) RF Connector
  • 20 Meter Waterproof Design (When Installed)

Note 1: The specifications and performance of this antenna are dependent on antenna matching network and counterpoise dimensions.

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