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.
7.6. Indoor antenna installation
Proper antennas shall be selected according to the site conditions and the requirement. And more than one
antenna can be used with the repeater, especially for repeaters equal with or over 20dBm, and 30dBm can be
connected with up to 10 antennas in order to send the signals to larger areas or distribute the signals equally.
Please consult our professional engineers about the solution if you want to connect more than one antenna.
1) Omni antenna (Indoor ceiling omni antenna or whip antenna), is suitable to be installed in the center and
radiate all directions.
