CATV system/ TO4FTO4F
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).
Since 1971, the objective of Naval Electronics has been to offer the best possible products for TV and Radio reception at sea. Naval began with omnidirectional antennas and is the world leader in this field of technology today. Now, with an expanded product range, the name Naval means much more than antennas. Naval operates in more than 40 countries and has installations on thousands of vessels all over the world.
