BROADBAND PLANAR SPIRAL ANTENNAS

Planar spiral antennas with a frequency range of 2 to 18GHz will measure approximately 20mm diameter.
Gain from 2dBiC to 7dBiC across the band.
Right or left hand circular polarisations.
Multi octave bandwidths.
HPBW is typically 55° to 80°.
VSWR 2:1 or better across the band.

Provides 360° hemispherical coverage for live video links.

BROADBAND and ULTRA WIDEBAND, MULTI-OCTAVE, EXTENDED PERFORMANCE OMNI ANTENNAS

Extended performance omni antennas feature up to 2 octaves within the range 1 50MHz to 4GHz.
1 to 2dBi gain across the band.
Fully efficient, vertically polarised biconical design for higher power rating.
Balanced design eliminates the need for a ground plane.
Maximum VSWR 2.5:1 across band.
Rugged, with glass fibre radomes.
Elevation HPBW typically 60° to 80°.
