DatasheetVHF/UHF/L-Band Antenna
30 to 512 MHz & 960 to 2500 MHz
SKU: 21-50-123
The 21-50-123 is a high speed passive blade antenna providing full VHF, UHF and L-band performance in a double raked design. It can be used as a footprint replacement for a number of existing V/UHF and VHF/UHF/L-band antennas including AS3191, this antenna is built using a high strength resin/glass composite radome encapsulating a wide band, specially contoured radiating element.
Used in conjunction with Cooper Antennas Ltd 21-80-04, 21-80-03 filters and/or 21-80-71 diplexer, this antenna can provide separate V/UHF, MIDS/JTIDS and Data link outputs for simultaneous operation of all three systems (see over).
- Swept back blade
- Dual V/UHF and L-band outputs
- Suitable for Mach 2
- Gain in UHF and L-band similar to stand-alone blades
- Nominally Omni pattern thru band
- Footprint replacement for AS3191
- Designed to MIL-STD-810 environmental conditions
