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
The most widely used types of feed line are coaxial cable, twin-lead, ladder line, and at microwave frequencies, waveguide. Particularly with a transmitting antenna, the feed line is a critical component that must be adjusted to work correctly with the antenna and transmitter. Each type of transmission line has a specific characteristic impedance.
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.
