HLR430 Antenna
Rotatable Log Periodic Antenna 3.8-30MHz

The HLR430 is a high-performance rotatable log periodic designed to provide reliable link establishment over short, medium and long distances.


  • Characterized by its high gain performance whilst maintaining an excellent front to back ratio, the HLR is capable of providing coverage in excess of 5000kms.
  • The broadband feature enables transmission from 3.8-30MHz and reception from 2-30MHz.
  • A high-performance rotary joint enables continuous rotation with a complete 360º turn achieved in two minutes.
  • The rugged design of the antenna ensures its suitability for cyclonic wind velocities.
