Question
Why were segment couplers needed for adding a few RF devices to a TP installation, especially an existing one?
Answer
C — Previously the media coupler had to be installed in the main line, but a single-line installation (e.g. 1.1) has no main line - so a way to branch a TP line off for RF devices was needed.
