The systems will be used to provide AES secure digital voice and data connectivity throughout the US and its outlying territories. Mr. John Eschenfelder, General Manager of Barrett Communications USA, commented “This is an historic delivery for Barrett USA cementing its position as a trusted partner to the US Federal Government.”The systems include Barrett 4075 HF high power systems which are available in 500W and 1kW configurations and increase the strength of transmissions.
