Ultra wideband omni antenna for DAS applications
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 omni-directional antenna, model OA-0.4-6.0V/2028, covers 380 MHz to 6000 MHz. It features vertical polarisation and -1 to +5 dBi 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 352 mm (14 inches) diameter by 182 mm (7 inches). Being light weight (0.97 kg), 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.
