Amplifier | ||||
Trunk amplifier | ||||
Trunk amplifier is mainly used to compensate the signal loss of indoor distributing system, bi-directional amplifying uplink | ||||
and downlink signal, improving the voice, solving the high-building ping-pong effect and easy dropped line. | ||||

Dual band trunk amplifier is available | ||||
such as GSM+DCS/WCDMA+DCS/CELL+IS95/GSM+CDMA | ||||
Top Tower Amplifier | ||||
Top Tower Amplifier is used to amplify the uplink signal before the loss of cable, improving the S/N and sensitivity. It provides | ||||
cost-effective solution for expanding uplink coverage and improving uplink call quality. | ||||
