Protection from Lightning
US National Electric Department of Energy Handbook 1996 specifies that radio and televisión lead-in
cables must have adequate surge protection at or near the point of entry to the building.
The code specifies that any shielded cable from a detached antenna must have the shield directly
connected to a 10 AWG wire that connects to the building ground electrode.
The ground wire shall be terminated with UL listed lug with a diameter of 0.2 inch (5.2 mm).
The ground lug will need to be suitable for terminating on aluminum materials, such as the use of an
aluminum connector and aluminum ground conductor.

to be used only when installed in accordance with the instructions outlined in this manual. Failure to
comply with these instructions may also void the user’s authority to operate this device and/or the
manufacturer’s warranty
Consecutive AP Connection
Consecutive connection is done by plugging data crossover CAT5 cable between SU and consecutive
MU. This cable will also provide power redundancy to the units.
Total length of all wires should not exceed 300 feet each (91 meters).
Synchronization
Sygnus SHC was designed to work with co-located antennas. That means that two or more units can
be mounted close to each other.
Time synchronization allows reusing frequencies between co-located links and configured with the
WebGui Interface.
The synchronization signal is generated by an external GPS (1 PPS).
To configure time synchronization, set all MUs to synchronization Enable and Slave mode.
