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
In a radio antenna, the feed line (feedline), or feeder, is the cable or other transmission line that connects the antenna with the radio transmitter or receiver.In a transmitting antenna, it feeds the radio frequency (RF) current from the transmitter to the antenna, where the energy in the current is radiated as radio waves.
A Goubau line or Sommerfeld–Goubau line, [1] or G-line for short, is a single-wire transmission line used to conduct radio waves at UHF and microwave frequencies. [2] [3] [4] The dielectric coated transmission line was invented by F. Harms [5] in 1907 and George J. E. Goubau [6] in 1950, based on work on surface waves on wires from 1899 by Arnold Sommerfeld.
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 ...
