Trunk amplifiers are generally used to cooperate with micro-cell base stations or repeaters to solve indoor signal blind spots. They adopt a dual-port full-duplex design, built-in power supply, easy installation, high reliability, and are compatible with digital and analog systems.
It has the advantages of light weight, small size, simple and convenient installation.
The working frequency band can be customized according to customer needs.
