Class Information
Number: 343/829
Name: Communications: radio wave antennas > Antennas > Fractional, multiple, or full wave length linear type > With grounding structure, including counterpoises
Description: Subject matter together with structure including ground or structure most closely associated with or simulating ground, and such structure being connected to the terminal of the signal receiver or source opposing the active antenna terminal (i.e., having the signal receiver or source interposed between the active antenna and this structure), for establishing a reference potential level for operating the active antenna.
