VHF/UHF Airborne Blade Antenna

The 21-50-115 is a low profile blade antenna providing excellent VHF and UHF performance in a small passive design over the entire frequency band of 30-512 MHz. Radiating element design is optimized to provide excellent omni-directivity in azimuth over the full band in a low drag, elliptical shaped structure.

Construction uses a glass epoxy radome bonded into an aluminum alloy base plate which carries a TNC type connector.

The antenna is fully sealed and foam filled for long term reliability and is suitable for rotary and fixed wing aircraft operating in excess of Mach 1. z

  • Low height 9.4"
  • Very wide band with no tuning required - continuous frequency coverage
  • Designed to MIL-STD-810
  • Fully environmentally sealed
