APGK (2-12) antenna set

APGK (2-12) antenna set

Small-size NVIS antenna is designed to be used as part of field, semi-stationary and stationary HF radio transmitting centers to provide omni-directional radio communication (without blind zones) for short range in various climatic conditions (including Northern, mountainous and seismic regions).


Area

Full package includes:

·        NVIS frame antenna with tuning unit (TU)

·        Control unit

Control unit is placed in control room and provides coupling of the product according to the control commands with transmitter and communication system. This device also implements an algorithm for switching the operating frequency and provides the possibility of manual switching.

Antenna does not generate spike noises.
