Abstractive and selective properties of radio antenna circuits

This paper is an analytical study of the power abstractive and selective properties of simple series radio antenna circuits.¹ It does not deal with the properties of coupled circuits, or of amplifying circuits, or of differentially connected circuits which utilize a difference in the direction of propagation of the waves from the correspondent station and the interferent sources to reduce interference. A discussion of the selective properties of the simple series circuit is a necessary, or at least a very helpful, preliminary to the treatment of coupled, amplifying and differentially connected circuits.
