Expanding the television outputs

You may connect as many as 8 more H838s to the outputs of a master H838 for a
total of 64 television outlets. The longest recommended coax run should not
exceed 150’. (That is a total of the coax from master to slave and from slave to TV.)

The H838 hub work like a zero-loss splitter. The signals

automatically appear on the outputs at an FCC legal level.

Typical remote control

To control your video devices, add a modulator with IR repeating, an IR target and
an IR emitter. Point a remote control at the target in the bedroom and IR pulses
are repeated by the emitter, controlling the DVD player in the den.
Any or all of the television ports may have targets connected.

Expanding the modulator inputs

Add a model H881 active combiner and a single modulator input becomes eight.

Things To Watch For:
Herringbone interference on modulator channel (diagonal lines):

You may have chosen a
channel number that is not completely vacant. Distant UHF stations may not be watchable, but
will cause interference if you try to create a new channel at the same frequency. Also, cable
companies often have extra signals where there should be none. Try moving the modulator
channel to another number. You may have to add a low pass filter to remove the cable company
noise. If the filter does not work, try adding a DC-block to remove common mode interference.

Herringbone interference on many channels, including modulator channels (disappears
when you remove the CATV/antenna feed)

: The RF amplifier can be overloaded by
abnormally strong signals. Often, you can cure the problem with a simple attenuator. Use a
variable attenuator and try to find a signal level where the interference just disappears.
Sometimes, the problem is one station is far stronger than the rest. In this case, attenuating all
of the signals with a simple attenuator may cause the desired stations to be weak (snowy). You
must reduce the strength of the only offending station. A common FM trap will help if the
problem is a nearby FM tower. If the problem is a nearby TV station, often the station
management can provide suitable filters.

FCC Requirements:

THIS PRODUCT COMPLIES WITH FCC REQUIREMENTS.
A SYSTEM USING THIS DEVICE WILL COMPLY WITH FCC REQUIREMENTS.
USE ONLY VIDEO MODULATORS THAT COMPLY WITH PART 15
OF THE FCC RULES AND HAVE 25dBmV MAX OUTPUT LEVELS. FAILURE TO
DO SO MAY VOID THE USER’S AUTHORITY TO OPERATE THIS EQUIPMENT.
THE H838HHR IS SUITABLE FOR USE WITH AN ANTENNA OR WITH
CATV SYSTEMS.
THE H838BID IS SUITABLE FOR USE WITH CATV SYSTEMS.
