HT-78A conforms to rigid military standards:
Mil-Std-810E tests for reliability under harsh environments and Mil-Std-461C tests for EMI/EMC.

It is also fully compatible with old generation radios such as AN/PRC-77, AN/VRC-12, etc

Military Band Secure Hand Held Transceiver NHT-78A

The Nabishi NHT-78A DIGITAL VHF handheld radio developed for the modern tactical environments, the radios are DIGITAL or ANALOGUE switchable. It provides secure and reliable voice and data communication over the entire military band of 30-88MHz with 12.5 or 25KHz step. Some of the HT-78A powerful features include: the capability to transmit both data and voice, securing communication with scrambler, selectable tone signalling, versatile scanning options, dynamic antenna matching circuit, auto battery detection, etc. The unit is encrypted with a full 256-bit AES Algorithm for operation in Digital & Analogue mode for secure voice communications. The NHT-78A is complimented by and fully compatible with our Mobile MR-3088 military mobile radio.

NHT-78A conforms to rigid military standards: Mil-Std-810E tests for reliability under harsh environments and Mil-Std-461C tests for EMI/EMC. It is also fully compatible with old generation radios such as AN/PRC-77, AN/VRC-12, etc.
