ULTRA WIDEBAND and MULTIBAND ANTENNAS
Effective countermeasures for field operations are becoming mandatory as commercially available RF products continue to be used by insurgents to set off IEDs.

Denying use of the RF spectrum to the enemy is of critical importance. As RF sources and amplifiers are developed to cover wider bands at higher power, it is important that antennas are developed in parallel.
The antennas must cover all specified bands, peak gain must be on the horizon, and they must be small enough for use by foot soldiers and rugged enough for vehicle applications. We have a portfolio of ultra wideband omni antennas in the range 150MHz to 40GHz to cover all of the bands in which high power amplifiers operate.
Multistack omni arrangements have been developed as well as specific antennas with high gain for cellular band countermeasures.
ULTRA WIDEBAND OMNI ANTENNAS
Biconical omnis that are fully efficient, vertically polarised Bandwidths from 3:1 to 30:1 are achievable
Frequencies from 100MHz to 18GHz
Ground plane independent
Elevation HPBW typically 30 to 60 degrees
Typically 0 to 2dBi gain across the band
Excellent azimuth patterns
Peak gain on horizon across all bands
MULTISTACK OMNI ANTENNAS
Wideband omni antennas can be 'stacked' so that several antennas may be designed into a single housing, which provides a single mounting point on any vehicle
New feed through technology allows multiple antennas to be co-located
Overlapping frequencies for multiple applications
High isolation between bands 200W per band simultaneously
Good return loss across all bands
Directional, ultra wideband, high power, circular polarised antennas are available. This range is continually expanding with new developments undertaken to meet customers' deployment requirements.
