Effective countermeasures for field operations are becoming mandatory, as commercially available RF products continue to be used for IED triggers. Denying enemy operators their use of the RF spectrum 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 similarly, in parallel. Such 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.
Chelton have a proven portfolio of ultra wideband (UWB) omni antennas, in the range 150MHz to 40GHz, to cover all of the bands in which high-power amplifiers operate. We have developed multistack omni arrangements, as well as specific antennas with high gain for cellular band countermeasures.
Wideband omni antennas can be 'stacked'; we can design antennas so that several can be built into a single housing, which provides a single mounting point on any vehicle. This is further enabled by new feed-through technology allowing the co-location of multiple antennas within the same radome. Features and benefits include:
A wide range of directional, ultra-wideband, high power, circular polarised and spiral antennas are also available from Cobham Antenna Systems. This range is continually expanding, with new developments undertaken to meet customers' deployment requirements. Features and benefits include:
