This document is about the SAILOR Nargentus AM-FM TV Antenna Installation and Maintenance Manual.
This document is the installation and maintenance manual (document number 98-137318-B, released 24 September 2014) for the SAILOR Nargentus antenna system, published by Thrane & Thrane A/S, trading as Cobham SATCOM. It is intended for installers of the system and service personnel and covers unpacking, installation, antenna assembly, installation of the PS 16 Power Supply, and maintenance including troubleshooting and returning units for repair.
The SAILOR Nargentus is described as a terrestrial omni-directional active AM-FM-TV (0.1-790 MHz) radio/TV antenna for maritime use, for receiving digital and analogue signals. It is aimed at vessels operating near the coast or in harbour with one or two radio/TV sets, such as coasters, fishing-boats, tugs, pilot service vessels and rescue cruisers. The antenna uses a low-noise amplifier powered via the coaxial cable, has a reinforced fibre-glass composite housing with inner parts embedded in polyurethane foam, and includes filters to suppress interference from VHF telephones, AIS transmitters and LTE wireless communication.

It is an active AM-FM-TV antenna covering 0.1-790 MHz: AM 0.1-26.5 MHz and FM/TV 40-790 MHz, with an average amplifier gain of 25 dB.
The kit includes red and black cables (500 mm) with fuse holder and fuses, self-tapping screws, F connectors, a 75 Ohm terminating resistor, a 1.5 m F-IEC cord for the TV set, and a holder for the coaxial cable.
It is an installation manual intended for installers of the SAILOR Nargentus system and service personnel.
Filters with high efficiency suppression prevent interference from VHF telephones, AIS transmitters and LTE wireless communication, with wave traps at VHF 156 MHz, AIS 162 MHz and LTE(800) 800-1000 MHz.
