4.3 Outdoor Unit
Before installing the MDR5800 Outdoor Unit, ensure that a suitable mast is used for
the antenna and that the Outdoor Unit installation is firmly in position. The pole
diameter must be between 50 and 102 mm.
CAUTION – ENSURE THAT THE POLE IS EARTHED FOR LIGHTNING
PROTECTION.
4.3.1 MDR5800 Outdoor Unit
Follow these steps to install the MDR5800 Outdoor Unit:
1. Install the system antenna.
2. Adjust the mounting bracket to be slightly bigger than the pole diameter.
3. Secure the mounting bracket to the pole.
4. Secure the Outdoor Unit to the bracket using the screws on each bracket.
5. Connect the Outdoor Unit to the pole electrically by connecting the earth cable
or strap between the pole earth and the Outdoor Unit earth point.
6. Connect the type-N RF output connector to the system antenna through an in-
line lightning protection unit in areas with lightning activity.
7. Cover the connectors using an ultra violet protective, self-vulcanising tape.
4.3.1.1 RF Connection
1. The RF port is an N-type female connector.
2. The N-Type connector is used to connect to the antenna, typically using coaxial
transmission line.
3. 1/2" or 5/8” coaxial cables are recommended. Coaxial cable that is 7/8” or
larger can exhibit moding at 5.8 GHz and is not recommended for 5.8 GHz
radios.
4. Do not use right angle N-type connectors with the 5.8 GHz radios: they may
present high loss at 5.8 GHz.
5. Do not use low quality cables. Some cable types, such as RG-8, may have too
high a loss at 5.8 GHz.
