INSTALLATION AND DEBUGGING
Preparation before Installation
Project Reconnaissance Design
a. Confirm the coverage area of broadband tri band mini repeater
b. Forecast coverage effect and confirm project
By reconnaissance on the spot, you can make sure outdoor antenna locations and
then confirm the indoor antenna as per the coverage area you want to cover. The
indoor antenna should be installed in the central point of coverage area. In order
to make project plan more correctly, it is often to go on field intensity coverage
prediction on these areas. Confirm mini repeater working parameter, such as gain,
output power and antenna model and so on to supply theory basis for system
adjustment and testing.
Installation Process
Design, install and debug antenna and feeding system
Antenna and feeding system design and installation are so important parts of tri
band mini repeater project. Antenna and feeding system relates directly to using
outcome from wide band tri band repeater. When doing the design, please pay
attention to the distance between outdoor and indoor antenna, insulation degree and
port VSWR. Cable jamming network should be connected into grounding system
