ANTENNA TYPES

Ultra Wideband Antennas - Cavity Backed and High Power Spirals

Cavity Backed Spiral

• Very wideband: 0.5 to 4GHz, 2 to 18GHz
• Can be used stand-alone or as part of a DF (Direction Finding) array
• Phase and/or amplitude matched to provide accurate DF
• 0 to 5dBiC gain
• Circular polarisation
• HPBW 50° to 90° across the band

High Power Spiral

• High power and ultra wideband
• Directional, with gain up to 8dBiC
• Circular polarisation provides better chance of jamming
• Flat panels can be disguised if necessary
• Bi-directional option
