F.A.Q – FREQUENTLY ASKED QUESTIONS

INSTALLING MULTIPLE UNITS? –

Please see page 13 “Installing Multiple Units” Each unit MUST have its own frequency and major

channel number.

QUESTIONS ABOUT THE DIFFERENT STANDARDS? -

Check out our explanation of each standard below. Please refer to your TV manual for the supported

Tuner Formats such as Digital ATSC or Digital QAM j.83B cable

WHAT IS THE ADVANCED MENU? –

The Advanced Menu allows adjustments of PSIP and other tweaks such as the Units RF strength. Please

look at page 12.

TRYING TO MIX SIGNAL WITH OTHER MODULATORS? –

Please ensure you don’t set our unit on the same frequency as your other modulators as well as

balancing the RF level. If you broadcast our unit on the same frequency as your other modulators it will

cancel each other out or cause unwanted results on your TV image such as two channels split on one

screen. Please see Page 14 for more information.

MIXING OVER THE AIR ATSC SIGNALS WITH OUR UNIT?

Please see page 14 for more information.

MORE THAN TWO UNITS ONLY PICKING UP A FEW CHANNELS AND NOT ALL?

Ensure that each unit has its own Frequency, Major, Minor, and Channel Name.

If you have multiple units connected with a splitter or coax combiner, please check the signal coming

from the combiner directly plugged into a TV and scan for channels. You should be able to pick up all the

channels. If not, we might need to amplify the signal. Coax has a lot of variables to account for, so we

always need to start from the source and work our way up. Sometimes cheap splitters or combiners can

introduce harmonics that create noise causing the TV to skip a channel because it’s too dirty of a signal

to pick up. It is rare but happens from time to time with cheaper coax combining equipment.

BALANCING SIGNAL - SIGNAL NOT REACHING ALL THE TVS

This could be that the signal strength isn’t enough to reach all your TV sets. For example, if you have 12

TVs in a chain and the last 3 won’t pick up your channel, then you can buy an inexpensive coax amplifier

from online and add it to the coax line on the unit to boost the signal to reach the last 3 TV sets.
