solution for multiple output LNB and switch

box applications. The ZXHF5000 includes a 4

by 2 switch with 19dB of positive gain which

can be connected directly to the output of the

LNB or switch box eliminating the need for

cable drive amplifiers.

The ZXHF5000 includes all the control required

for voltage and tone based systems providing a

reliable and highly integrated solution.
