Original Product Page

F20-TB triple band repeater is to support any three mobile band existing in the world to help end users to improve mobile signals for much better phone call quality and smoother data transmission. It is designed to support coverage area up to 500~1500 square meters with proper engineering. Below are the main features.

1.It is an ideal solution for providing a cost effective improvement in cellular in-building coverage of a home, office, restaurant or building, in the quickest time possible.

2.Manual gain control (MGC) available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintenance

3.To maintain safe and specific output signal levels and give alarms on self-oscillation, the repeater has built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.

4.Auto shut off function available for both uplink and downlink to avoid deep self-oscilation from jamming the towers, saving your trouble from operators.

5.Multiple phones and other handheld devices throughout a building can benefit from a wireless repeater.

6.Supports up to (280) users / calls simultaneously.
