This is my new dipole antenna. (Figure not in scale.) The elements are J-shape folded in a vertical plane. It is now more compact and looks better with its simpler form.
Obviously, the antenna should work less better than before, because it occupies less volume in the air. The VSWRs are below 1.5 for all the bands from 80 m to 6 m, but became slightly higher in most bands.
I had some QSOs with domestic stations on both 40 m and 30 m bands, and I will keep this shape of the antenna for a while.
