G5RV Antenna Homebrew
The idea of using ladder line as a transformer is not new by any means. This antenna, in the 102' length, is designed to perform well and offer multi-band operation while offering the ease of using coax to feed it
G5RV Antenna
About 102 feet long. It was fed with 30-feet of 300-ohm transmitting type ladder line
G5RV multi-band antenna
In describing the theory of operation, it has been assumed that it is generally possible to erect the antenna at an average height of about 10.35 m 34 ft which happens to be the optimum radiation efficiency on 160, 80 and 40 m bands for any horizontal
G5RV Formula a simple multiband antenna
Mr. Varney's G5RV version used open wire 600 ohm feed line all the way to the transmatch instead of the short section of 450 ohm window line and 70 feet of 75 ohm coax that most of us know today
