This and the 1912 RMS Titanic rescue brought the field of marine radio to public consciousness, and marine radio operators were regarded as heroes. By 1920, the US had a string of 12 coastal stations stretched along the Atlantic seaboard from Bar Harbor, Maine to Cape May, New Jersey.

The base station is one end of a communications link. The other end is a movable vehicle-mounted radio or walkie-talkie. [6] Examples of base station uses in two-way radio include the dispatch of tow trucks and taxicabs. Basic base station elements used in a remote-controlled installation. Selective calling options such as CTCSS are optional.
The military station operator will announce the specific amateur-band frequency being monitored. Usually, MARS stations are located in military and government installations such as The Pentagon, [5] Fort Huachuca, Andrews Air Force Base, Nellis Air Force Base, as well as Navy bases such as NAS Whidbey Island and several Coast Guard locations.
The PRC-160 is the manpack HF radio for the Harris Falcon III family of radios. It replaces the earlier AN/PRC-150 , with a smaller form factor and lighter weight than its predecessor, and being capable of 4th Generation Automatic Link Establishment (4G ALE), achieving data transmission speeds up to 10 times faster.
The PRC-163 is one of the Handheld, Manpack & Small Form Fit (HMS) components [3] of the Integrated Tactical Network family of radios, [1] the U.S. Army's modernization strategy for tactical radios. It is a member of L3Harris' Falcon IV family of tactical radios, and the successor to the Falcon III-family AN/PRC-152 Multiband Handheld Radio.
The station's current antenna was built in 1972; it consists of two guyed masts, each 458.11 metres (1503 feet) tall, which are configured as umbrella antennas. They are fed by an overhead cable, fixed to a tall mast at one end, and at the opposite end to a smaller grounded mast near the helix building via an insulator.
Communication with submarines is a field within military communications that presents technical challenges and requires specialized technology. Because radio waves do not travel well through good electrical conductors like salt water, submerged submarines are cut off from radio communication with their command authorities at ordinary radio frequencies.
