COMBINING SERVICE PROVIDERS SIGNALS OR ATSC WITH YOUR DEVICE
For Combining ATSC (Over the Air channels) you must find the frequencies that are
used by your local stations. This information can usually be found online by searching
for, “(insert your local area) ATSC frequency chart.” This will give you a nice table that
shows all the Frequencies used in your area. Find the ones that are not used and write
those down. Set your device(s) to those unused frequencies. Test using your Test TV.
Note:
For installers, it is recommended but not necessary to use a Spectrum analyzer
to see the spectrum available to you to make the installation easier. This does not
require an expensive unit to do this. Any Spectrum tester to view the available
frequencies will help you in the process.
For combining with cable Service provider the same rules apply. You can contact your
local service provider of your basic cable to find the frequencies that they use and fine
the ones that are available for you to use. If you wish to inject into a Digital Cable
Converter box or STB (set-top box) most of the time the service provider will include a
channel you may broadcast onto or some
providers require a specific PID’s to be set
which can be set in the
ADVANCE MENU
in order for the Set to box to be able to read
the channel.
