SAC and Local Partner Balkantel, Complete Turn-key NDB Project for BULATSA

With local partner Balkantel, SAC completes a turn-key NDB Project for the Bulgarian Civil Aviation Authority BULATSA.

The turnkey project included the removal of existing outdated equipment and replacement with our 125 Watt Transmitters, PC1000/C4 Antenna Tuning Units, and Remote Control Units.

SE125 Dual IP66In 2020, Southern Avionics was awarded a procurement for a quantity of six SE125 Dual IP NDBs by BULATSA but the Covid-19 pandemic began in the midst of this project so implementation was delayed.

We had to work very closely and carefully with BULATSA, and our partner Balkantel to coordinate and handle the deliveries, SAT, re-installation, installations, flight checks, and, site acceptance tests and commissioning.

The Balkantel Sites are noted as: BOZ, DWN, GNA, KMN, WAK.

We are providing an extended warranty and look forward to working with BULATSA for their future requirements.

Our partner for this job, Balkantel Ltd of Sofia, Bulgaria, and Mr. Nikola Dourchev Commercial Director have proven to be an excellent and highly skilled company to be associated with.
