Omnidirectional C/D Band Antenna
900 - 2000 MHz
The 21-40-90 is a wideband omnidirectional antenna intended for helicopters, vehicular and ground installations where no ground plane is available.
The design comprises an array of wide band dipoles connected and phased in such a way as to provide nominally omnidirectional radiation in azimuth with maximum gain at or near the horizon.
Construction uses an epoxy-glass radome with internal foamed in place elements for maximum environmental protection. The antenna has an aluminum base plate with a single, TNC connector.
- Wide frequency coverage thru C/D Band
- Excellent gain thru band
- Vertical polarization
- Ground plane independent
- Designed to MIL-STD-810 environmental conditions
