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. Chinese or PHILIPS push-pull module design with high performance
3. Total seal waterproof shell made of new-type aluminum alloy
4. Optional power supply mode: local power supply (220V)/central power supply (60V)
5. Mobile relay structure is applied to amplifier inner equalizer, attenuator, bi-directional filter and amplifying module, which guarantees a flexible and convenient operation
