3) Keep horizontal cables straight and fasten them stably with a fixing clip every 1 to 1.5 meters, with a proper
stress.
4) Bind and fasten vertical cables every two to three meters to avoid damaging cables or connectors owing to
their own heavy weight. Take back the cables and re-lay them when you have difficulty in pulling them, and
avoid using a strong force to pull them.
5) Separate RF cables from power cables. Take proper isolation measures if they have to be placed on the
same cable racks owing to the site condition restriction.
6) Correctly fasten all connection parts of the whole system, from the antenna to active interfaces to passive
interfaces, and keep electrical interfaces well contacted. Give waterproof treatment to outdoor connection
parts.
7) Take lightning protection measures for the
antenna and feeder system in accordance with the design
requirement. Avoid deforming the antenna feeder where grounding clips are placed, and give waterproof
treatment to the feeder.
8) Keep exposed indoor cables in good order. Install PVC troughs or tubes if the exposed cables are more
than 1 meter long. Place small passive RF parts such as power splitter in cable troughs.
9) Process both ends of RF coaxial cables as follows:
Keep the same redundant cable length and keep the length of stripped cables to agree with the
corresponding connectors.
Use a proper force to cut the jacket layer or insulation layer and avoid damaging the braid shielded net and
cores.
Weld cores firmly and smoothly with a proper amount of solder, without solder projections or nodules.
Assemble coaxial cables strictly in accordance with the installation specifications.
Keep a moderate length of heat-shrinkable tubes and heat-shrink the tubes evenly when adding
heat-shrinkable tubes to the end of cables.
Protect the ends of cables against water and dampness. Use waterproof tape to give waterproof treatment
to exposed cable ends. Cut off the end if it is dampened or water-soaked.
8.5. Indoor antenna installation
Proper antennas shall be selected according to the site conditions and the requirement.
1) Omni antenna (Indoor ceiling omni antenna or whip antenna), suitable to installed in the center and radiate
all directions
