4.1.3.
RF Cable Installation Guidelines
Required:
●
For all coaxial connections to/from the Repeater - high performance, flexible, low loss 50Ω
coaxial communications cable.
●
All cables shall be weather-resistant type.
●
Cable length - determined by the Repeater installation plan. When calculating the cable
length, take into account excess cable slack so as not to limit the insertion paths.
4.1.4.
F/O Cable Installation Guidelines
Use the following over the complete link between the Remote and OMU:
●
Use SC/APC connectors (8 degree angle) for all connections
●
Cable length - determined by the Remote installation plan. When calculating the cable
length, take into account excess cable slack so as not to limit the insertion paths.
Recommended fiber-optic cable:
●
Single-mode type fiber 9/125
4.2. Service Antenna Requirements
a. The installer is held accountable for implementing the rules required for deployment.
b. Good engineering practice must be used to avoid interference.
c. Output power should be reduced to solve any IMD interference issues.
The Service antenna type (i.e. the antenna feeding the mobile/remote units) depends on the design of the DAS.
4.2.1.
Required Antenna Information
The following antenna requirements, specifications and site considerations should be met:
●
Type of installation – DAS/Radiating Cable
●
Service area type and size
●
Antenna type and characteristics
●
Height
●
Length and type of coaxial cable required for connecting the antenna to the Repeater and
the attenuation.
