With high selectivity character, Channel Selective Repeater provides superior out-of-channel suppression to avoid interfering with adjacent channels.
It can be applied to the urban RF environment where suffered from interference caused by complicated donor signals. The Channel Selective Repeater is also an ideal solution for rural area.
These Channel Selective Repeaters are designed with a waterproof enclosure which can endure almost any outdoor condition. With advanced and user-friendly Operation & Management System (OMS), engineers can monitor and configure multiple repeaters remotely as long as they can log in to the OMS system via a web browser legitimately.
