DL6FBL's "Big Quad" (I)
Three elements for 10/15/20m and two (fullsize) elements for 40m on a 24m-Tower. The boom length is 8.5m. Each fiberglass spreader measures 7.8m from the centerpoint - this makes 15.6m from end to end or 10.5m vertically and horizontally. The end points of the boom are used for guying the Quad in itself with 3mm polyester rope. The antenna is fed with four seperate lines of coax (quarter wavelength 75 Ohm coax in line). About 0.3m over the boom there is a single six metres long 144 MHz yagi from Mư.
