When the distance between the antenna and the RRU/SRXU is shorter than 14 m, the RRU/
SRXU is directly connected to the antenna through the antenna jumper.
When the distance between the antenna and the RRU/SRXU is longer than 14 m, the antenna
jumper should be shorter than 2 m. If you prepare the jumper by yourself, it is recommended
that the feeder jumper be 2 m long at most. Ensure that the antenna jumper is connected to
the feeder before being connected to the RRU/SRXU and the antenna.
