Double isolated TV/Radio Outlets N1

Naval double galvanically isolated outlets N1 with IEC 9.5 mm connectors or F-connectors are a new series that have been designed especially for marine use and covers the complete TV-Radio frequencies of 0.1–890 MHz world-wide. N1 is galvanically double isolated to avoid problems with interference and grounding which are quite common in larger systems. The outlet has improved RL and surge protection witch makes it especially suitable for digital signals. N1 is for star net only, where each output from a tap-off or a splitter can feed max. one N1. The frame called N, for surface mounting, is designed to fit all the Naval outlets. It is anufactured in white plastic RAL 1013. The standard supply of Naval outlets includes a full size white cover RAL 1013 (76 x 76 mm). N1 need not be terminated.
