Early style antenna switch box. Console systems are played on a television. As such the systems need a way for the information they process to show up on the screen, and for the audio to be played through a sound system. Originally this was done through an antenna switch box. [8] Later this was changed to a coaxial cable setup called a RF ...
It was packaged with the DS TV [NTR-016], DS TV dedicated cover [NTR-017], and DS TV Dedicated External Antenna (with suction panel) [NTR-025]. The external antenna plugged into the side of the DS TV itself through a standard headphone jack. A series of three suction cups could be used to attach the wire to a window or other smooth surfaces.

This Royal Navy model is typical of B–T goniometers. The two sets of field coils and the rotating sense coil are visible.. A Bellini–Tosi direction finder (B–T or BTDF) is a type of radio direction finder (RDF), which determines the direction to, or bearing of, a radio transmitter.
Hexbeam amateur radio antenna. A hexbeam, or hexagonal-beam, is a type of a directional antenna for shortwave, most often used in amateur radio. The name comes from the hexagonal outer shape of the antenna. It may also sometimes be known as a W-antenna, referring to the shape of the driver. The design looks something like an upturned umbrella.
A reconfigurable antenna is an antenna capable of modifying its frequency and radiation properties dynamically, in a controlled and reversible manner. [2] In order to provide a dynamic response, reconfigurable antennas integrate an inner mechanism (such as RF switches, varactors, mechanical actuators or tunable materials) that enable the intentional redistribution of the RF currents over the ...
Homebrew, when applied to video games, refers to software produced by hobbyists for proprietary video game consoles which are not intended to be user-programmable. The official documentation is often only available to licensed developers, and these systems may use storage formats that make distribution difficult, such as ROM cartridges or encrypted CD-ROMs.
Remote electrical tilt is abbreviated as RET and it is part of the Antenna Interface Standards Group's open specification for the control interface of antenna devices. [ 2 ] Occasionally, mechanical and electrical tilt will be used together in order to create greater beam tilt in one direction than the other, mainly to accommodate unusual terrain .
The antenna elements fed by a Butler matrix are typically horn antennae at the microwave frequencies at which Butler matrices are usually used. [4] Horns have limited bandwidth and more complex antennae may be used if more than an octave is required. [5] The elements are commonly arranged in a linear array. [6]
