VOR/ILS Antenna - 21-14L

The 21-14L and 21-41LT are airborne antenna systems intended for VOR/ILS applications. Each antenna system comprises two centrally fed half loop antennas that must be fed in antiphase for correct function. The 21-14LT complies with the requirements for efficiency, gain and polarization of RTCA/DO-196. It further complies with para 3.1 of ICAO Annex 10. Each half loop is formed from stainless steel tubing with a fibreglass dielectric junction at its mid point. A T-adapter is needed to connect opposing antennas.

  • Lightweight tube antenna.
