Description

Bi Directional Push Pull Distribution Amplifier are professional quality, two-way broadband indoor distribution amplifiers. These amplifiers are ideal for multi-channel RF distribution systems the input source is a "cable drop" or the output of an MATV/SMATV/CATV headend.

Dual push-pull hybrid modules to keep good C/N when gain control and tilt control are used.
Passive and active return path.
Built-In variable gain & slope control and output test ports.
Line transient protection.
Aluminum chassis for excellent heat dissipation.
Good for CATV/MATV/SMATV head end signal launching or signal level boosting in signal distribution.
Different frequency range available: 550MHz, 860MHz, 1000MHz.
