Rotatable receiving and transmitting log-periodic antenna is designed to operate as part of semi-stationary and stationary radio transmitting centers and HF radio communication systems in omnidirectional trunk communication systems on medium and long ranges up to 8000 km. This antenna is designed to operate in various climatic conditions up to wind area IV and glaze area IV.
Rotatable log-periodic antenna occupies minimal space when installed and can be deployed multiple times. Lifetime of these antennas is not less than 8 years.
