My base antenna is an original DBJ-1 antenna made by Doctor Ed Fong himself or one of his students. This antenna does not need a ground plane nor ground plane radials.
The black tape for waterproofing. It is now hung a tad higher than in this picture.
I assembled it slightly differently than most, by having the plug on a “branched” piece of pipe instead of on the bottom. This, so the plug wouldn’t conflict with the fastening method. The segment of pipe below the antenna inside of it is reinforced with an extra piece of (smaller diameter) pipe.
