Description

Key Features of the MCA-40860

* See back cover for instructions on how to change the splitter

The dual output MCA-40860 is a superior quality push-pull wall­mounted distribution amplifier producing signals with low-noise
and harmonic distortion. The The MCA-40860 serves as an ideal
distribution system amplifier for heavily loaded MDU (multi­dwelling units, i.e. apartment complexes), commercial areas,
educational institutions, hotels, and broadband CATV or SMATV
systems. The distribution amplifier is capable of broadband
135-channel operation over the 40-860 MHz range.

The MCA-40860 is housed in compact, aluminum chassis that
provides excellent heat dissipation and allows the amplifier to be
operated at high ambient temperatures with no degradation of
performance or reliability.
