When possible coil all cables near this unit, and always use drip loops. See figure 1.
Connect the lowest and smallest antenna to port one, or short port one and use ports 2-8
for antennas if possible. See the Lightning Protection section of this manual.

Wiring
Wiring is very simple. Be sure any wire you use is suitable for the environment it will be
placed in. Do not bury above-ground rated wires, and do not use indoor non-UV resistant
wires in direct sunlight.
Three insulated wires should connect terminals A, B, and C on the relay box to terminals
A, B, and C on the indoor control head. The ground return can either be made through the
coaxial cable shield, or through additional conductor(s) in the control wire.
We recommend following a standard resistor color code format for wiring. Use brown for
A, red for B, and orange for C if possible. Otherwise, start with the lowest standard color
and work upwards. If you do this with all cables, you will rarely need to keep wiring
notes.
