The Musa connector (for Multiple Unit Steerable Array/Antenna) is a type of coaxial ("coax") connector, originally developed for the manual switching of radio signals. It has a characteristic impedance of 75 Ω, [ 1 ] and was adopted for use in the emerging television broadcast industry.
An antenna tuner, a matchbox, transmatch, antenna tuning unit (ATU), antenna coupler, or feedline coupler is a device connected between a radio transmitter or receiver and its antenna to improve power transfer between them by matching the impedance of the radio to the antenna's feedline. Antenna tuners are particularly important for use with ...
An Auston switch (also known as a photoconductive switch) is an optically gated antenna that is commonly used in the generation and detection of pulsed terahertz radiation. [1] It is named after the physicist David H. Auston who first developed the technology at Bell Labs in the 1960s.
The radio frequency current from the transmitter is supplied to the antenna through a cable called the feedline.The antenna tuning hut contains a matching network made of high wattage capacitors and inductors (coils) that in combination match the antenna's impedance to the feedline, to efficiently transfer power into the antenna.
Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
The first plaque was launched with Pioneer 10 on March 2, 1972, and the second followed with Pioneer 11 on April 5, 1973. In May 2017, a limited edition of 200 replicas engraved from the original master design at Precision Engravers was made available in a Kickstarter Campaign, which also offered laser-engraved replicas.

An antenna rotator (or antenna rotor) is a device used to change the orientation, within the horizontal plane, of a directional antenna. Most antenna rotators have two parts, the rotator unit and the controller. The controller is normally placed near the equipment which the antenna is connected to, while the rotator is mounted on the antenna ...
Optonica amplifier (SM-3636) and tuner (ST-3636) from 1978. The Optonica brand was created and first launched by Sharp of Japan in 1975 to compete in the high-end audio market along with established brands such as Sansui Electric, Sony, Panasonic, Sanyo, Yamaha, Nakamichi, Onkyo, Fisher Electronics, Technics (brand), Pioneer Corporation, Kenwood Corporation, JVC, Harman Kardon and Marantz.
