MF antennas for NDB

MF T-antenna is designed for equipping NDB "PRA-Parsek" with power of 500W for aircrafts homing with airborne bearing equipment sensitivity not worse than 50 µV/m

Area

Full package includes:

·        antenna (radiator array and suspension rigging for 2 masts)

·        2 masts

·        HF counterpoise (ground or lifted)
