Antenna Types & Theory

Helix

HELIX ANTENNAS

Helix antennas are a traditional way of producing circular polarisation for a directional application, over a broad bandwidth, typically 25%.

Applications include outside broadcast and video surveillance where circular polarisation helps mitigate the effects of multi-path in a highly reflective environment.

  • Frequencies up to 4GHz
  • Gain up to 17dBiC
  • Hand held, pole mount or shrouded
  • Good axial ratio, right or left circular polarisation
  • N-type connectors and maximum VSWR of 1.5:1
  • Light weight, low wind loading
  • Optional mounting kits available
