Installing the Equipment Cables

The VSAT VS61 comprises two major sections: The Above-Deck Equipment (ADE) is
composed solely of the antenna radome assembly, which is mounted outside. The Below-
Decks Equipment (BDE) includes the Antenna Control Unit (ACU), satellite modem(s), and
all other items of ancillary equipment.
The ADE is connected with the BDE by two coaxial cables; the type of cable to be used
depends on the length of cable required.
NOTE: Unused coax connections (on the connector bracket) MUST be terminated with
a 75 ohm terminator.
NOTE: We recommend cable type according to cable length, as follows:
-within 20m: RG6
-within 50m: RG11
-within 100m: LMR400
-within 200m: LMR600
NOTE: Impedance of cable is 50ohm. Also you can select the other cable types.
However we recommend all attenuation of cable is under 20dB at 2.5GHz.
NOTE: When installing the cables, avoid the use of excessive force. Exercise caution
during installation of the cables to ensure that they are not severely bent (within the
assured bend radius), kinked or twisted, and that the connectors are not damaged.
NOTE: Make sure that the cables have been passed through watertight fittings and/or
that they will prevent water from entering the ship once their installation has been
completed. After the cables have been routed and adjusted for the correct cable length at
each end, seal the deck penetration glands and tie the cables securely in place.
