…or invalidated depending on your point of view. Presenting the... Two new patents address shortcomings of the 84 or more year old traditional J antenna design. This effort features the following highlights. The research includes extensive J antenna myth busting, validating the concerns trumpeted by many over the years, using method of moments and finite-difference time-domain simulation techniques confirmed by real antenna chamber measurements. The utility patent voluntarily catalogs and reviews many published papers and related patents. The addition of a mast decoupling stub mitigates the propensity of the J antenna to energize a conductive mast. No more does the J antenna require an ideal length of conductive mast to perform correctly. The parallel nature of the mast decoupling stub maintains the slender nature of the J antenna. Internalizing the feed line of hollow pipe J antennas eliminates the traditional, but famously awkward, external feed line dressing. Additionally this internal feed approach performs double duty by naturally decoupling the feed line from the antenna. The improvements maintain the J antenna's notable direct electrical connection through robust antenna conductors to the mounting structure and, hence, ground from dc to just below the primary design frequency.

At least this one works.
