GPS RECEIVER INSTALLATION (G OPTION)
The 5600MSC units (with the +G option fitted) are designed to work with the Trimble Accutime 2000
Smart Antenna that can be located up to 1000 feet from the 5600MSC unit. The Smart Antenna
houses the GPS receiver, antenna, power supply and other support circuitry in a sealed, shielded, self-
contained unit with a digital interface to the main unit. The GPS Smart Antenna also receives power
from the main unit through the connection cable.
2.5.1. Mounting the GPS Smart Antenna
The smart antenna's enclosure is completely waterproof and is designed for outdoor installation. It is
protected against jamming signals and thus is suitable for reliable operation in most environments.
Select an outdoor location for the antenna, like the roof of your building that has a relatively
unobstructed view of the sky. Dense wood and concrete or metal structures will shield the antenna
from satellite signals. The antenna can receive satellite signals through glass, canvas and thin
fiberglass; thus it may be mounted inside a skylight, if an outdoor location is not possible.
The smart antenna is an active-head antenna. For optimal performance, locate the smart antenna as
far as possible from transmitting antennas, including radar, satellite communication equipment and
cellular transmitters. When locating the antenna near a radar installation, ensure that the antenna is
positioned outside of the radar's cone of transmission. Follow the same guidelines when installing the
antenna near satellite communication equipment. For best results, mount the antenna at least ten feet
away from satellite communication equipment. Do not mount the antenna near high vibration areas
such as fan or motor housings, or near sources of heat such as exhaust stacks.
Consider the length of the cable run when selecting the location. A 50 foot cable is supplied; however,
longer cables are available on special order from the factory. You may also wire a straight-through
extender cable to extend the able distance up to 200 feet. The smart antenna is designed for a pole
mount with a 1" - 14 straight thread, which is a common marine antenna mount. For stationary
installations a 3/4" pipe thread can be used, but a 1"-14 straight thread is recommended. Pole
mounting is illustrated in Figure 2-3.
