NDB NAVYRA-500 is the result of many years of experience of our company working in the field of radar and radio navigation technology.
It is an aerial non-directional beacon that can be used for both civilian and military deployments. We supplied this equipment for example for: AERO TRADE, a.s., MO of the Slovak Republic, MO of Uzbekistan, MO of Azerbaijan.
NDB NAVYRA-500 is an effective, reliable, dual approach radio beacon used as air navigation to ensure the landing of aircraft, it can be used for both stationary and mobile stations. It can be operated manually on site or remotely via intelligent software with self-control functions. It can work with "T" type antennas, UZA or other antennas with a grounding system.
Our "T" type antenna is intended for connecting a non-directional beacon (NDB) for broadcasting a radio signal in the frequency range from 190 to 1750 kHz. The antenna works as a grounded counterweight system and is mounted on a 12m or 24m long steel tower, a warning light (230V / 50Hz) is installed on top of the tower antenna in accordance with ICAO rules.
