NMO mount connector (new Motorola mount), removable mobile antenna connector uses a 3 ⁄ 4 inch (19 mm) mounting hole and has a large base with a 1 1/8" – 18 tpi thread for attaching the antenna. SC connector, screw version of C connector [not to be confused with the fiber optic connector of the same name]
NMO may refer to: Neuromyelitis optica, also known as Devic's disease or Devic's syndrome; N-Methylmorpholine N-oxide, an organic compound; Nitronate monooxygenase, an enzyme; Normal Move Out, in reflection seismology; National Measurement Office, a government agency in the United Kingdom; New Motorola, a mobile antenna connector
The connector reliably carries signals at frequencies up to 100 MHz. [1] The coupling shell has a 5 ⁄ 8 inch 24 tpi UNEF standard thread. [4] The most popular cable plug and corresponding chassis-mount socket carry the old Signal Corps nomenclatures PL-259 (plug) and SO-239 (socket). [12]
The antenna is resonant at this length, so its input impedance is purely resistive. The input impedance has capacitive reactance below 1 / 4 λ and inductive reactance from 1 / 4 to 1 / 2 λ. The gains given in this section are only achieved if the antenna is mounted over a perfectly conducting infinite ground plane ...
A horn antenna has a flaring metal horn attached to a waveguide. It is a simple antenna with moderate gain of 15 to 25 dBi, used for applications such as radar guns, radiometers, and as feed antennas for parabolic dishes. Slot Consists of a waveguide with one or more slots cut in it to emit the microwaves. Linear slot antennas emit narrow fan ...
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 ...
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 ...
A typical mast radiator and antenna tuning hut of an AM radio station in Chapel Hill, North Carolina, U.S.. A mast radiator (or radiating tower) is a radio mast or tower in which the metal structure itself is energized and functions as an antenna.
