It is necessary if you want to plug the 82163 TV output to your TV.
To my limited knowledge, the 82163A TV output has the big part of the RF modulator in it but it need the VHF adapter to finish the job.
I would assume that some old TV did had a VHF adapter in it with a RCA plug but I do not remember having seen that.
I have never opened an VHF adapter, but since it is passive, I would assume that it only contains basic components in it. (resistors, caps and coils)
