Chapter 10 Main Antenna Feeder System Installation

10.4.8 Installing the Indoor Jumpers
Indoor cabinet-top jumpers are used between the lightning arrester connected to the
main feeder and the rack. Usually the finished 2m cabinet-top jumpers are used, or the
jumpers can be prepared on site according to the actual length required.
If the 2 m finished jumpers are used, they can be directly installed between the
lightning arrester and the rack top.
If the jumpers are prepared on site, 1/2'' feeders should be prepared through cutting
according to the specific length of each jumper. Assemble proper feeder connectors
onto both ends of the feeders according to the feeder connector assembly instructions,
and connect the jumpers between the lightning arrester and rack top.
