Frequency Agile UHF and Cable TV Channel Video Audio Modulator
Modulate video and left/right audio signals of a VCR, satellite receiver, or security camera to UHF or CATV selected channels. This installer friendly modulator is frequency agile and allows the signal to be placed on any free UHF channels 14–78, or CATV channels 65-94 and 100-135. Simply push a button to select a channel. An easy to read LED display shows the channel that is selected. When used with a front door camera, see who is at the front door from any TV in the house by conveniently changing to the modulated channel. (Note: The audio signal is the left and right combined, therefore it is not a true stereo modulator.)
Make any Empty Channel your own! Use it to send Programming through your Home or Office Distribution System. Pipe your own In-House TV Channel into every room. Simply combine the Output with Your other TV Programming Source before the Amplifier for Seamless TV Channel delivery. Handy for Front Door Security Camera, Satellite TV Receiver and VCR Output. Takes Video and Audio Inputs, Selectable/Programmable TV Channel Output!
TV Channel Insertion
Analog TV channels can still be used and mixed into your premise (Home or Office) Distribution System. Some insertions and combining can be simply by using a 2-way splitter in reverse (the two outputs are now two inputs). Passives like cable TV splitters are not directional in that regard, their directionality comes into play by increasing port to port isolation (between outputs) thereby reducing port to port feedback and interference. If you are mixing two sources that do not have any channels (Frequencies) in common and each occupies a different portion of the spectrum, the 2-way splitter can work. If you are combining satellite and Off Air TV antenna signals and wish to do so cleanly, with the hopes of separating them again at the other end of the cable (done to use one cable coming in the house rather than two), you would use a combiner separator used for that purpose, If you want to combine a DVD, VHS Tape, Xbox or similar channel 3/4 device output into your TV antenna or cable TV feed, you would select a CH 3 or 4 combiner. If you have a cable or Satellite feed and you want to mix video coming from a camera or similar device, understand that it is raw and isn't "Modulated onto a TV channel yet. You will need a Modulator that is frequency agile so you can find an "Empty" Channel or piece of the spectrum that is not currently being used by the feed and simply use a 2-way to combine them. Plug the feed into your TV, select the appropriate feed typoe from your setup menu and see what empty channels exist. Even HDTV's still tune analog channels, so you get bang for yuour buck. Sometimes mixing VHF and UHF antenna feeds (with a 2-way) is advantageous as the collected signal strength is additive. If it is not additive, but is out of phase and reduces signal strength, then use a UHF/VHF Separator/Combiner for this purpose.
