Omni Antenna, 340 - 470 MHz, 2 dBi, Weatherproof Sealed Spring Base
  • Elevation Pattern: Referenced to +5 dBi
  • Engineering Drawing: All dimensions are in inches

Product Overview

Southwest Antennas Part # 1001-220 is an omni-directional half-wave dipole antenna that operates from 340 - 470 MHz and features 2 dBi of peak gain across the operational frequency range of the antenna.

The integrated sealed spring base allows the antenna to bend and flex with impacts and return to its original vertical operating position, helping to prevent damage to the mated RF connector and attached radio. The environmental seal allows for outdoor operation and prevents fouling of the spring by dirt, sand, mud, rain, or other debris.

The antenna's flat black finish and rotating black chrome Type-N(m) RF connector allow this antenna to be deployed for low visibility operations.

  • Broad Band Coverage
  • 340 - 470 MHz
  • 2 dBi Omni Radiation Pattern
  • Rugged Construction
  • Low-Glare Black Radome
  • Black Chrome Rotating Type-N(m) RF Connector
