VHF/UHF/L-Band Antenna

The 21-50-102 is a high speed passive blade antenna providing full VHF, UHF and L-band performance in a double raked, low RCS design. Intended as a bolt on replacement for existing UHF/L-band and VHF/ UHF/L-band antennas, this antenna is built using a high temperature resin/glass composite radome encapsulating a wide band, specially contoured radiating element. A high isolation diplexer is built into the machined aluminium base which is specifically designed to withstand direct lightning strike attachment. Lightning and P-static protection is further enhanced by all elements being DC grounded. 

  • Swept back blade
  • Isolated V/UHF and L-band outputs
  • Suitable for Mach 2+
  • Gain in UHF and L-band similar to stand-alone blades
  • Excellent Omni pattern thru band
  • Drop on replacement for existing UHF/L-Band Blades
  • Designed to MIL-STD-810 environmental conditions
