ANTENNA TYPES
Helix Antennas
• 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
• Maximum VSWR of 1.5:1
• Light weight, low wind loading
• Optional mounting kits
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.
