Mark 32ALC is an omni-directional wide band antenna (0.1-26.5 and 40-890 MHz) TV-FM-AM, for maritime purposes. It is based on a construc-tion of loop antennas coupled to four band amplifiers three of which have individual automatic level control units - ALC’s. The ALC’s have very high dynamic range,and keep the antenna free from intermodulation even in the vicinity of high power transmitters. High efficiency suppression filters prevent interference from VHF telephone and AIS transmitters. Mark 32ALC is made of ABS plastic and filled with polyurethane foam. Mounting base in saltwater proof special alloy and bolts in stainless acid proof steel. Mark 32ALC is tested by “Det Norske Veritas” for the same approval as for radar equipment.

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.

Naval digital and analogue splitters SP2F and SP4F 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.

The PSA 350S/ALC compact power supply and amplifier is designed to supply power to the Mark- and VPA-active antenna series as well as amplifying Radio and TV signals for distribution in a medium-sized network. The unit is equipped with an S-Band input for distribution of cable-TV channels or modulated satellite channels. A separate Ch38 Input allows connecting a VTR/DVD. An inbuilt Automatic Level Control reduces gain in case of overload. Gain can also be set manually. Like all other Naval products, the PSA 350S/ALC series is designed to meet the special requirements of world-wide marine use. See overleaf for further details of specific applications. The PSA 350S/ALC accepts 117 and 230 VAC

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 manufactured 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.
