The U.S. Signal Corps used the term "sets" to denote specific groupings of individual components such as transmitters, receivers, power supplies, handsets, cases, and antennas. SCR radio sets ranged from the relatively small SCR-536 "handie talkie" to high-powered, truck-mounted mobile communications systems like the SCR-299 and large microwave ...

This system, known as HICOM, was activated in 1957 and operated parallel to the existing communications channels. Later, the Commander in Chief, U.S. Pacific Fleet (CINCPACFLT), established an additional parallel circuit known as the "Atomic Strike Coordinator Circuit." It was determined that even more rapid communications would be necessary.
Goliath transmitter was a very low frequency (VLF) transmitter for communicating with submarines, built by Nazi Germany's Kriegsmarine navy near Kalbe an der Milde in Saxony-Anhalt, Germany, which was in service from 1943 to 1945.
Prior to the creation of the DHFCS, the Royal Air Force (RAF) and Royal Navy (RN) operated their own independent high frequency (HF) communications systems. The RAF's Strike Command Integrated Communications System (STCICS), later known as Terrestrial Air Sea Communications (TASCOMM), operated from six sites within the UK whilst the RN system had twelve sites.

Multifunction Advanced Data Link (MADL) is a fast switching narrow directional communications data link between stealth aircraft. [1] It began as a method to coordinate between F-35 (the Joint Strike Fighter), but HQ Air Combat Command wants to expand the capability to coordinate future USAF strike forces of all AF stealth aircraft, including the B-2, F-22, and unmanned systems.
Common Data Link (CDL) is a secure U.S. military communication protocol. It was established by the U.S. Department of Defense in 1991 as the military's primary protocol for imagery and signals intelligence. [1] [2] CDL operates within the K u band at data rates up to 274 Mbit/s. CDL allows for full duplex data exchange.
Umbrella antennas developed from large multi-wire capacitive antennas used by Guglielmo Marconi during his efforts to achieve reliable transatlantic communication. One of the first antennas that used this design was the tubular 420 foot (130 m) mast erected in 1905 by Reginald Fessenden for his experimental spark gap transmitter at Brant Rock ...
