Ultra Wideband Omni Antenna Developed for DAS Applications

Cobham Antenna Systems, Microwave Antennas (formerly European Antennas Ltd) has developed a new Ultra Wideband and compact Omni-Directional antenna.

Ultra Wideband and Compact Omni-Directional Antenna

Originally developed for an airport application, the antenna is required to support DAS applications covering PMR, TETRA, Cellular, Wireless LAN and WiFi communications systems.

This new Omni-Directional antenna, model OA-0.4-6.0V/2028, is ultra wideband (380MHz to 6000MHz). It features vertical polarisation and -1 to +5dBi gain across the band. The omni pattern has very low ripple, and unlike other similar antennas does not require any additional ground-plane to be able to operate across its full band.

Dimensions are 352mm (14 inches) diameter by 182mm (7 inches). Being light weight (0.97kg), the antenna can be ceiling mounted using a variety of optional mounts.  The protective radome is manufactured from fire retardant material and the unit has been SAR tested.

Further variants are planned which will have high impact radomes and can tolerate high power for applications in potentially hostile environments where RF counter measures may be necessary.
