Installing the RTN 380H
2
1+1 Scenario
Retain removed caps for future use.
1. Cover unused ports with caps/PG covers.
2. Before installing the RTN 380H, remove the protective cover and film on the antenna port. Otherwise, the signal transmission will be affected.
3. Different methods can be used to change the polarization direction of antennas. If the method provided in this document is not suitable for the type of antenna you have, use the method provided in the installation manual delivered with your antennas.
4. The polarization direction of antennas is vertical by default. If the planned polarization direction is horizontal, change the polarization direction to horizontal.
5. If an antenna with a diameter of 0.2 m, 0.3 m or 0.6 m is used in a direct mount scenario, you may install the RTN 380H on the antenna and then hoist them both into position on the tower.
6. Before installing a cable, bind the cable section that links the cable connector to the pole. This will protect the cable connector from damage. Be sure that the length of cable running from the binding point to the RTN 380H is sufficient to attach the cable connector to
the Ethernet service port on the RTN 380H.
7. To facilitate installation, install cables from left to right.
Installation procedure
1 Follow the antenna use instructions to
install the antenna.
2 Optional
: Change the polarization direction
of the antenna to horizontal.
Apply petroleum jelly around the exterior

8 Install a GE cascading optical fiber.
•Apply anti-corrosion measures
to the GE cascading optical fiber.
9
Optional : Install an outdoor fiber.
• Install an outdoor fiber on the RTN 380H.
• Lay out the outdoor fiber.
•Attach a yellow outdoor label to the fiber according to the plan.
•Moistureproof the fiber.
Do anti-corrosion treatment for COMBO ports, P&E ports
10
and GE ports.
11
Waterproof the ground clip.

Check the installation.
The RTN 380H can receive power signals from
either the DC power port (PWR) or the P&E
port. Power over the P&E port is used as an
example.
