21-48L Datasheet

VOR/LOC/GS loop antenna – 21-48L

The 21-48L is an airborne antenna system intended for VOR/ILS and glideslope applications. Each antenna system comprises two centrally fed half loop (21-48L-1()) antennas, that when mounted on the aircraft must be fed in antiphase for correct function. Each half loop is formed from stainless steel tubing with a fibreglass dielectric junction at its mid-point. From the mid-point a co-axial cable extends internally and exits through the mounting flange. The half loops are connected together via a T adaptor.
