The G5RV antenna is a dipole with a symmetric resonant [1] feeder line, which serves as impedance matcher for a 50 Ω coax cable to the transceiver. [ 2 ] [ 3 ] Origin
Date/Time Thumbnail Dimensions User Comment; current: 19:11, 13 January 2013: 713 × 349 (6 KB): 2A4Fh56OSA: Impedance of the feedline now corresponds to the given length.
The G5RV antenna is a dipole antenna fed indirectly, through a carefully chosen length of 300 Ω or 450 Ω twin lead, which acts as an impedance matching network to connect (through a balun) to a standard 50 Ω coaxial transmission line. The sloper antenna is a slanted vertical dipole antenna attached to the top of a single tower. The element ...
Discone made of solid copper sheets, theoretically covering 700 MHz to 2 GHz. A discone antenna is a monopole version of a biconical antenna , in which one of the cones is replaced by a disc. It is usually mounted vertically, with the disc at the top and the cone beneath.

The G&SWR was formed in 1850 from a merger of the Glasgow, Paisley, Kilmarnock and Ayr Railway (GPK&AR) and the Glasgow, Dumfries and Carlisle Railway (GD&CR). A number of other companies were absorbed by the G&SWR or its predecessors, including the Ardrossan Railway, the Paisley and Renfrew Railway and the Kilmarnock and Troon Railway.

SWR is used as a measure of impedance matching of a load to the characteristic impedance of a transmission line carrying radio frequency (RF) signals. This especially applies to transmission lines connecting radio transmitters and receivers with their antennas, as well as similar uses of RF cables such as cable television connections to TV receivers and distribution amplifiers.
