GatesAir has won Phase-II of Bangladesh’s national HD radio rollout. The turnkey system comprises two self-contained FM radio stations with high-efficiency GatesAir Flexiva FAX air-cooled 10 kW FM transmitters, antenna systems, and all auxiliary and support equipment.

Bangladesh Betar, the only national government broadcaster serving Bangladesh, awarded the contract as Phase-I of the GatesAir-supported rollout moves forward. The initial phase, which covers the capital city of Dhaka, also includes two GatesAir Flexiva FAX 10 kW transmitters and is targeted for completion by the end of 2016. The Phase-II will cover the heavily populated cities of Mymensingh and Gopalganj, with an expected on-air date of June 2017. Both projects are especially notable as the first HD radio deployments in South Asia.

The GatesAir Exgine4 HD radio platform, which simplifies signal flow and connectivity across the architecture, will play a central role in each system. The complete system includes GatesAir’s FlexStar HDI-200 Importer and HDE-200 Exporter at the studio; and the FlexStar HDx exciter at the RF plant. The complete system supports all HD radio program audio and program-associated data over a single, bandwidth-efficient stream, with plenty of headroom to incorporate additional services in the future.

GatesAir’s ability to also provide turnkey services helped to cement the Phase-II contract win. Along with site planning, design, integration, and commissioning services, GatesAir has and will continue to provide extensive training services around system operation and transmitter maintenance both in Bangladesh and at its Quincy, Illinois, manufacturing center. The low-maintenance benefit will pay dividends for both Betar and the Bangladesh government moving forward. In addition to the Flexiva FAX transmitter’s compact footprint – a valuable asset given the limited real estate available in each RF plant – the latest-generation GatesAir Flexiva design minimizes internal parts, with common power amplifier modules and power supplies. This streamlining of parts and size also reduces weight, making single-engineer maintenance a reality for the Betar team – preserving valuable engineering resources for other needs.
