Coaxial cables are often joined with power cables for CCTV use, meaning that only one cable has to be run to provide a both video and power connections. [10] Twisted pair cables such as Ethernet cables are sometimes combined with fiber-optic cables. A common configuration is a four-pair Category 5 cable with two strands of multimode fiber optic ...
In stage lighting, [1] a multicable (otherwise known as multi-core cable or mult) is a type of heavy-duty electrical cable used in theaters to power lights. The basic construction involves a bundle of individual conductors surrounded by a single outer jacket.
Multi-mode fibers have a larger core that allows the propagation of multiple cylindrical transverse modes (Also referred as linearly polarized modes), in contrast to a single mode fiber (SMF) that only supports the fundamental mode. Each transverse mode is spatially orthogonal, and allows for the propagation in both orthogonal polarization.
OTA antennas are digital receivers that pick up signals broadcast by local TV towers, allowing you to watch local programming without cable. These antennas cost anywhere from $15 to $50.
An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. [1]: p.149 [2] The individual antennas (called elements) are usually connected to a single receiver or transmitter by feedlines that feed the power to the elements in a specific phase relationship.
The category of simple antennas consists of dipoles, monopoles, and loop antennas. Nearly all can be made with a single segment of wire (ignoring the break made in the wire for the feedline connection). [citation needed] Dipoles and monopoles called linear antennas (or straight wire antennas) since their radiating parts lie along a single ...
