Product Description

Applications

  • Transponder
  • Telephony
  • Data Link Sub System (DLS)
  • Drone Flight Control Systems
  • GRDCUS
  • BQM-34

The slotted blade or “bent stub” antenna provides both vertically and horizontally polarized components of radiated energy.  This feature fills in the antenna pattern hole typically exhibited by the 1/4 wave stub antenna.  The “bent stub” also provides a vertically polarized component when the aircraft is in a steep bank attitude.

Scalable to other frequencies for nominal engineering fee.  Add suffix letter “S” for stainless steel or “A” for aluminum configuration.

Standard Models:
