Marine Satphone InstallationMarineNet Provides installations and solid advice/consultations pertaining to proper installation of all equipment we sell. Our statement simply is "What good is good equipment if it is not installed properly and functional?" We hope our picture show will help give you some ideas on your installation.
End result of the Globalstar Antenna mounting. Stern rails were replaced during this installation and one was an extended corner stanchion built with a threaded top pipe for screwing on VHF antennas or the Globalstar Radome cover kit with it's threaded base. Note the height is just above any other metal work or Bimini top frame on the boat and far enough back to allow the boom to travel past the antenna. Coaxial cables are inside the mast that go down into the hull and then the most direct path to the Navstation. Note that if 30 foot cables (30 foot kit) are required, fishing the two coaxial cables through the support pipe becomes very difficult depending on the wall thickness of the stanchion/support pipe so do a dry run inserting one cable at a time through the pipe. DO NOT KINK THE COAXIAL LINES!!! They are very fine and require special handling at all times!
Custom Mounting Options Available MarineNet Wireless makes available custom mounting options for Globalstar, Iridium and other VHF or Satellite antennas such as the one shown above and below, by request. Please supply us with the dimensions and mounting base requirements for a quote. Contact MarineNet Wireless at: service@marinenet.net Below is a great example of a custom mounting bracket created by Sea Wiz Marine for the Globalstar 2900 "Stick" antenna on a 20 foot tall power boat mast. Note that it was impossible to mount this antenna anywhere else so proper detail in mounting resulted in very solid satellite service.
If you have questions or need consultation from one of our staff, you may set an appointment at: service@marinenet.net to arrange a time or location. (Florida: Stuart to Miami) or call 561-747-5686 2004 Copyright Marinenet Data Systems, Inc. |
End result
of onboard installation showing the Globalstar 1600 handheld Satphone in it's
docking station with handset to the left and the microphone for the speakerphone
to the upper right of the satphone. The speaker box for the speakerphone is 2
feet to the left out of sight and away from the microphone element for best
speakerphone results.
MarineNet
installers use an old phone company trick to minimize noise on wiring by simply spiraling
the wires together like this power cable as shown above. This is extremely
effective to reduce RFI noise generated by SSB transmitters, Inverters/Battery
Chargers etc. This should be done with all wiring on the vessel to reduce
overall electronic noise.
Underside
of the Nav. Station desk position (Small close closet) showing the Globalstar
control box (Brain box) to the right and data control cables approaching from
the upper left to the underside of the docking station above it. Keep wireless
bundled tight so they do not snag. White bar is for clothes hangers. Note the
two antenna coax and power cables leaving from the left center to lower left,
are secured along the path to prevent dangling in the way.
When
installing the docking station using self tapping stainless steel screws,
protect the connector in the bottom of the docking station bucket from wood and
metal shavings with rag or plastic. Make sure to remove any debris that may have
fallen into the docking station as this could destroy the connector on the
docking station or the satphone.
Close-up
of the antenna installation showing antenna (Black cone) with it's magnetic base
secured to the steel plate inside the middle of the enclosure with excess coaxial
cable exposed here. Spiral excess cable inside the Globalstar radome enclosure
after "hand tightening" the SMA coaxial cable connectors. DO NOT OVER
TIGHTEN THE CONNECTORS!!! Use pliers to just snug them up slightly. Use supplied
heat shrink or good 3M electrical tape. If you use tape, start wrap spiral below
the connection and work your way up finishing with several wraps above the
connection. Theory is if water penetrates a wrap it will weep outwards away from
the connection.
Close-up
looking down inside the base of the Globalstar Radome kit showing coiled up coax
ready for final covering. By this time you should have power run to the system
and perform a final check by making a phone call to Globalstar's 611 for testing
or, someone with a good ear! Once testing is done, put a thin bead of silicone
clear grease along the gasket of the lower cover shown here and secure the top
radome cover with stainless steel screws.
Globalstar's 2900 white "stick" antenna with custom 1" thick
offset bracket and coaxial cable connector box base with mast offset mounting
flange for this installation. Great care was taken to keep the antenna as high
as possible (Half the antenna is above the mast mass) and, away from the mast as
practical to minimize the masts "shadow" effect. Contact Sea Wiz
