Dave here is a Picture of a . . . 5/8 WL Ground Plane Antenna No it isn't. http://users.belgacom.net/hamradio/s...calantenna.htm "The "ringostar" based coil: Is made out of 26 cm of 2,5mm installation wire. Remove the isolation of the wire and tin with a soldering iron the entire wire. The coil is 1,2 turns and has a diameter of 5 cm. One side is connected to the antenna and the other side to the boom." . Note "Installation Instructions" of 5/8 wave vs 1/4 wave antennas. 1/4 wave verticals require a proper ground plane (radials or sheet metal) to approximate the other half of a center fed dipole. The 5/8 wave is already over a half-wave long; no plane required. The coax shield needs a ground, the antenna doesn't. http://www.diamondantenna.net/m285.html http://www.diamondantenna.net/hf6fx.html |
