Naval digital tap-offs TO4 and TO2 have been designed especially for marine use
and the complete TV/Radio frequencies of 0.1–1000 MHz worldwide. In order to avoid
interference due to connection between the splitter and the ship’s hull, the splitter base
is manufactured in plastic to make it double isolated. Unused outputs of tap-offs do not need to be terminated. The last line output has to be terminated with 75 Ohms terminating connector (e.g. 500.207).
