The vessels each displace 1,920 long tons (1,950 t) while measuring about 95 m (311 ft 8 in) in length and 12 m (39 ft 4 in) in width. [ 1 ] [ 2 ] The OPV will use the UNIted COmbined Radio aNtenna (UNICORN) NORA-50 integration mast, which has a bar-shaped dome that houses the antennas for tactical data link, Tactical Air Navigation System ...
In a review Michael McGoldrick wrote, "The Paceship PY26 has to be described as a big 26 footer. Many manufacturers would have marketed this boat as a 27 footer, as did Tanzer. And with a displacement of 6000 pounds, this boat is reaching the upper limits of what can be realistically pushed around with an outboard motor.
Naval Radio Transmitter Facility Aguada is a tall guyed radio mast erected by the United States Navy.It is used as a facility of the US Navy for ashore and U.S. and NATO ships, planes, and submarines operating at sea in areas of broadcast coverage near Aguada, Puerto Rico at by using radio waves in the very low frequency
A sailboat's mast is supported by shrouds (side-to-side) and stays (fore-and-aft) – nautical equivalents of guy wires.. A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure.
The antenna must be very large at the VLF frequencies used; the supporting masts are 250–300 metres (820–980 ft) high, and the topload is about 1,900 metres (6,200 ft) in diameter. The trideco antenna was developed for high power naval transmitters, which transmit on frequencies between 15 and 30 kHz at powers up to 2 megawatts, to ...
A modified mast antenna, usually grounded at its base, augmented by one or several parallel wires called "skirt wires" that attach to the mast part-way up the antenna. The skirt wires can attach at any height between part-way up and the top of the mast. One or more of the skirt wires is fed with the signal, similar to a gamma match.
If the mast has a long, thin cross-section and makes up a significant area of the airfoil, it is called a wing-mast; boats using these have a smaller sail area to compensate for the larger mast area. There are many manufacturers of modern masts for sailing yachts of all sizes, a few notable companies are Hall Spars, Offshore Spars, and Southern ...
Goliath used three umbrella antennas, which were arranged radially around three 210 metre tall guyed steel tube masts and were insulated against the ground. At their edges, these antennas were mounted on grounded 170 metre tall guyed lattice steel masts. Three of these masts carried two umbrella antennas to comprise 15 lattice steel masts. [6]
