Design patent USD798847S1

The USPTO recently granted a design patent application that coincided with the utility patent application concerning how to make a J-pole antenna mast mountable with the use of a simple stub underneath the primary J antenna components. The “copper cactus” never looked so good and this design patent protects the ornamental nature of this assembly. To wit…


If nothing else this patent nicely organizes numerous patent and non-patent citations and references important to understanding the “real” history of the J antenna.

A J antenna unfettered by its mounting mast.
