Above is an
example of repeater’s indoor application. The Yagi antenna is used as the donor
antenna, and it is placed outside of the building where it has easy access to the donor Node
B/eNode B. Signals from the donor Node B/eNode B is then introduced into the repeater. After
amplification by the repeater, signals are divided into several parts by splitters and sent to the
service antennas. The service antennas are placed inside the building where it can extend radio
coverage to the dead zones. The mobile signals are sent via the service antenna to the repeater
then to the donor antenna and back to the Node B/eNode B.
2.3 Basic Repeater System Components
Splitters
Splitters are isolated dividers that split or combine RF power. According to the coverage
requirement, splitter can distribute RF power into several paths to achieve coverage of each
area. In the meantime, mobile signals from different coverage areas are combined together and
transmitted into the repeater.
Antennas
Donor Antenna
Directional donor antenna, one for each repeater, is recommended to improve signal strength.
Service Antenna
The service antenna is directional whose half-power beam width is depending on coverage
requirements.
Coaxial Cables
1/2” and 7/8” coaxial cables (50Ω impedance)are recommended to use with repeater. These
