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
