VHF Marine Band Communications Antenna

The 21-20-26 is a lightweight marine band communications antenna having an overall height of only 254mm (10 inches). The glass loaded thermoplastic blade is constructed as a one-piece pressure moulding, with all RF matching elements incorporated on an internal, encapsulated printed circuit board. DC grounding gives this antenna maximum protection against p-static, and the high strength/weight ratio of the blade makes it suitable for aircraft operating up to Mach 1. 

  • Low silhouette, low height
  • Lightweight aerodynamic blade
  • Covers full marine band without tuning
  • Loss less matching circuitry
  • Designed to MIL-STD-810 environmental conditions
  • Footprint replacement for AT256
