Specifications of Tetra Band Selective Pico Repeater
Model: BT-7A20B/ BT-7A27B
The Pico Repeater provides an affordable solution to solve the indoor signal coverage problems due to signal fading and attenuation caused by architecture obstacles. And its easy installation and maintenance can help carrier get fast return.
The repeater is working as a relay between the BTS and mobiles. It picks up the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
The Pico Repeater can amplify the signal within the customized band.
Two signal ports with full duplex design
High system gain
Linear power amplification to effectively suppress inter-modulation and spurious emission
Smart Automatic Level Control (ALC) ensures output level stable and adjustable continuously
Unique color LEDs to indicate power supply and state and alarm
Simple installation with external AC/DC adapter
Applications
To expand signal coverage or fill signal blind area where signal is weak or unavailable.

Product Description
View of Repeater
PANEL View of Repeater
- It supports wall mounting installation, follow the instructions below.
- First of all, choose a mounting position for the Pico Repeater in indoor environment. And then align Pico Mounting hole on the wall and be marked
- According to formerly marking on the wall to drill the holes, and inserted the rubber plug in the holes.
- Use screws fix the Pico's mounting hole on the wall where Pico is going to be installed.
- The BTS port on Pico Repeater is connected to the donor antenna, MS port is connected to the service antenna.
- System is supplied by AC220V power via connection of the external extension power cable.
- The system works properly under the condition of having enough system isolation.
- With obstruction or no, it must ensure the distance of 5-30 m between the donor antenna and service antenna.
