AN/ARC-220 High Frequency Nap-of-the Earth Communications (HF NOE COMM)

The HF NOE COMM System is the product of a modified, non-developmental item (NDI) acquisition strategy. The aircraft radio will provide in excess of 0-300 km NLOS communications when SINCGARS, HAVEQUICK, and other LOS radios will not communicate over the required distance. A ground version of the radio (VRC-100) will simultaneously be fielded to aviation TOCs.

The AN/ARC-220(V) and its ground version, the AN/VRC-100(V) will replace the AN/ARC-199(V) and AN/VRC-86(V) respectively. Secure communications will be achieved through the use of the KY-100 Crypto Set. The AN/ARC-220(V)1 consists of three line replaceable units; a Receiver-Transmitter (RT), a Power Amplifier Coupler (PAC), and Control Display Unit (CDU). The AN/ARC-220(V)2 is for bussed (1553) aircraft and consists of just the RT and PAC. The AN/VRC-100(V)1 consists of the three LRU's housed in a metal casing along with a power supply and speaker. The AN/VRC-100(V)2 is the AN/VRC-100(V)1 mounted on a HMMWV along with associated brackets and antennas. The AN/VRC-100(V)3 is for Echelons Above Corps and consists of the AN/VRC-100(V)1 with the AS-3791/G Broadband Antenna.

Radio characteristics include: voice and data ommunications; 2.0000-29.9999 MHz frequency band; COMSEC provided by KY-100 AIRTERM; Automatic Link Establismment (ALE) to improve connectivity and user friendliness; anti-jam (ECCM) and anti-spoof (Link Protection) capabilities; 10/50/100 watt variable output power; GPS interface; embedded modem (75-2400 baud); and, ANVIS compliant lighting.
