7.0 Planning for Installation
Before installing the SG-2000, some pre-planning based on the capabilities and features
of this radio should be undertaken to ensure the best possible performance.
7.1
Location of Power Supplies
If you are installing your SG-2000 in a normal environment, such as a radio room of a
ship or in a room of an office building or home, placement of the power supply is not
critical as long as it is placed within 25 feet of the radio.
If you are installing the radio in a small boat, such as a cruising sailboat or an offshore
fishing boat, you may wish to consider an additional gel cell (sealed) battery for radio
operation. In this way, should the vessel take on water during a storm, the radio will
continue to be operational.
A good way to install such a system is to place the "radio battery" in the vicinity of the
radio and place an isolator between the radio battery and the rest of the battery system.
When connected to the vessel's main batteries, the radio battery will prevent the voltage
drop which may develop on long cable runs and will assure peak radio performance.
7.2
Control Head Placement
One of the advantages of SG-2000 / PRC-2250-MIL ownership is that control heads may
be placed anywhere within 50 meters of the radio unit. This provides a high degree of
installation flexibility. Consider some of the more common civilian uses.
Marine.
On a vessel, you may want to have a control head located at the bridge,
navigation station, in the cockpit of the vessel and perhaps in staterooms. If you are
planning extended cruising on a typical ocean-going sailboat, usually two heads are
planned, one at the navigation station and another in a watertight case in the cockpit.
This is because in most serious ocean cruising, the owner's stateroom is not used as
often as the navigator's quarter berth, usually located very close to the navigation
station.
Mobile.
Installation in a mobile environment is something else. If you are the only
radio operator on a small four wheel drive vehicle, such as a Chevrolet Geo Tracker,
which we use as a test bed for mobile systems, you will likely have a single control head
and this would be mounted on the dashboard using the 5-way suction cup mount.
If your mobile installation is larger, as in a bus or large recreational vehicle, you may
wish to have one control head in the rear area and another control head in the vehicle
