Dual band 900/FDD2600MHz digital band selective repeater designed for enhanced mobile signal coverage in weak or dead zones.

The Public/Private Network Repeater acts as a relay between the BTS (Public/Private Network) and mobile phones. It receives the strongest signal from the BTS via the donor antenna, amplifies the signal linearly, and retransmits it to weak/dead zone coverage areas via the transmitting antenna distribution system. Mobile signals are also amplified and retransmitted to the BTS in the opposite direction.
- Analog: Enhances signal strength by amplifying analog signals
- Digital: Amplifies digital signals by converting to analog and then back to digital
