    en.wikipedia.org/wiki/OceanGate

    Titan (known as Cyclops 2 until 2018) was the second submersible designed and built by OceanGate, the first privately-owned submersible with an intended maximum depth of 4,000 m (13,000 ft). [56] The viewport was rated to only 650 m (2,130 ft), and the engineer of the viewport also prepared an analysis from an independent expert that concluded ...

    The first full scale beam waveguide antenna was the 64 meter antenna at the Usuda Deep Space Center, Japan, built in 1984 by the Japan Aerospace Exploration Agency. [6] After the Jet Propulsion Lab (JPL) tested this antenna and found it better than their conventional 64-meter antennas, [ 7 ] they too switched to this method of construction for ...

    en.wikipedia.org/wiki/Slot_antenna

    Slotted array UHF television broadcasting antenna. As shown by H. G. Booker in 1946, from Babinet's principle in optics a slot in a metal plate or waveguide has the same radiation pattern as a driven rod antenna whose rod is the same shape as the slot, with the exception that the electric field and magnetic field directions are interchanged; the antenna is a magnetic dipole instead of an ...

  8. Moxon antenna - Wikipedia

    en.wikipedia.org/wiki/Moxon_antenna

    Moxon antenna for the 20-meter band.The antenna is the faint rectangle of wires held in tension by the bent X-shaped support frame. Moxon antenna for the 2-meter band. The Moxon antenna or Moxon rectangle is a simple and mechanically rugged two-element parasitic array, single-frequency antenna. [1]

  9. Radio telescope - Wikipedia

    en.wikipedia.org/wiki/Radio_telescope

    Although the dish is 500 meters in diameter, only a 300-meter circular area on the dish is illuminated by the feed antenna at any given time, so the actual effective aperture is 300 meters. Construction began in 2007 and was completed July 2016 [9] and the telescope became operational September 25, 2016. [10]
