ZBL43D Series Bi-directional Outdoor Amplifier

Description                                                  

ZBL43D high-performance amplifier can be applied to 550MHz, 750MHz or 862MHz CATV bi-directional transmission system to compensate the RF signal loss on the cable transmission network.

Features

1 Compact in size with full function

2 PHILIPS or MOTOROLA push-pull module design with high performance index

3 Total seal waterproof shell made of new-type aluminum alloy with high quality of airproof and waterproof.

4 Optional power supply mode: local power supply (220V)/central power supply (60V)

Mobile relay structure is applied to amplifier inner equalizer, attenuator, bidirectional filter and

amplifying module, which guarantees a flexible and convenient operation.
