(under subclass 188.1) Subject matter including means for converting the carrier wave frequency to some other frequency by combining it with another frequency.
(1) Note. The converting means may, for example, be a separate frequency band converter, connected between the antenna and the receiver input for adapting a receiver operative in one frequency band (e.g., VHF) to receive signals in another frequency band (e.g., UHF).
