Mount the GPS antenna on an antenna mast (recommended) or on the peak of a building. The GPS
antenna kit (P/N no.: m-MK-AMC-40-1) includes special mounting brackets. For the mast, use 1-inch
(2.54-cm) diameter water pipe which is rigid enough to withstand high speed winds without flexing.
The steps needed to assemble the kit are as follows (as per given figure):
1. Clamp the GPS antenna on the mounting bracket with a retaining nut.
2. Attach the mounting bracket to the pole (P/N: m-AR-01-01) using two guillotine-style U bolts and
four hex nuts.
3. Connect the Type N male connector (antenna cable) to the antenna connector.
4. To ensure a trouble free installation the strain must be taken off the Cable by looping the cable.
•
Use GPS antenna cable supplied from factory or as
per recommended in manual. If antenna cable other than
recommended is to be used, contact Masibus Customer
Service representative.
•
Do not cut the antenna cable to shorter its length. In-
stead, bundle the excess cable to shorten antenna cable
length.
•
The model MC-1-DE requires a 5 Volt-compatible an-
tenna. Antennas not rated for 5 V will be damaged.
•
Use a splitter to connect a single GPS antenna to
multiple GPS TIME SYNC UNIT MC-1-DE units. Avoid
using BNC “T” connectors.
GPS related Accessories
The following options/accessories can be ordered:
1. Protect against lightning and field-induced electrical surges.
2. Connect multiple GPS TIME SYNC UNIT MC-1-DE receivers to a single antenna.
3. Extend the range of the GPS antenna cable.
1. Lightning Arrestor
Lightning may damage GPS system components and receiving equipment, even without a direct hit,
resulting in costly repairs and critical interruption of service. The lightning arrestor is designed to work
in conjunction with a low-resistance, low-inductance ground to protect your GPS receiver and ele-
ments of the antenna system from lightning discharges and field-induced electrical surges. In-line
lightning arrestors are mounted between the antenna and the point where the cable enters the build-
ing and require no additional power or wiring except the ground lead.
2. Antenna Splitter
An antenna splitter may be used to drive multiple GPS receivers using a single antenna. With built-in
amplification to overcome splitter losses, the Active Splitters may be conveniently cascaded without
adding separate amplifiers and bias-tees between splitters. Power is conveniently obtained from the
GPS receiver(s) connected to the amplifier, eliminating the need for a separate dc power supply and
wiring.
3. In-Line Antenna Amplifier
In-line amplifiers overcome signal attenuation in by amplifying the GPS signal. Use the in-line amplifi-
er for cable runs of 100 to 200 meter. Please contact a masibus Sales Representative for information
on how to extend the distance from the antenna to the receiver.
