LEGAL: The FCC requires you to apply for a Broadcaster's Liscence if your signal is stronger than 300 feet, or 100 meters in Canada (apply to your com branch).
I actually figured out, through trial and error, how to build a TV broadcaster, with common Radio Shack equipment.
You will need a Composite-to-RF Converter, to broadcast non-RF content on TV. This is not needed if you are using an RF source. It's output is the channel this will work on.
Where it says OUT TO TV, or TO TV, hook this signal to your first amplifier (a 20dB adjustable one recommended). From the output of this amp, attach it to the input of the next amplifier (a 10dB will be fine for a typical suburban install). At this point, if you are to get a liscence, or results are too weak, repeat with a third amplifier (ifyou can't get a 20dB one, and you're stuck with 10dB or lesser). Finally, attach the output of the final amp to a set of COLLAPSED rabbit-ears (another gain control. Adjusting length adjusts output).
This will work with analog signals, but if you have anything that outputs digitally in RF, it should work as well.
The following is a setup for use on channels 3 and 4. Higher channels, will require more amps, and more power, especially UHF.
USING AN OUTDOOR (Arial) ANTENNA FOR THE TRANSMITTER NOT RECOMMENDED. Output will be too weak for good use, and stronger signals may go past 300 feet. This is explained below:
This is where you hook up your device (game console, DVD player, etc.), and place the broadcaster and antenna next to the TV to use this device. Set the TV to the channel used, and fully stretch rabbit ears flat, to receive best signal nearest that of a direct connection. If it's too snowy, adjust the gain. If it hums and the colors are weak, reduce the gain until it looks correct.
Next, try this out of the farthest TV, within 50 feet, and see if it gets a USABLE signal. If the picture is snowy, in color, and the sound crackles a little, you have it setup PERFECTLY! The idea is to spy on people, and to have "good enough" results on the far end of the house.
NOTICE: This setup (demonstrated) goes up to 50 feet with collapsed rabbit ears. FOR THE SAKE OF DEMONSTRATION, it was applied to the roof antenna, and went well beyond the 300 feet maximum. This is NOT how I use it. Do not try this, even if the overall distance is proper, because the TV's in the house will likely not get good results. ALWAYS used rabbit ears for the transmitting antenna.
At the end, I rushed it, because 15 minutes came fast. I stopped the video at 15 minutes exactly, or so the camera said. Guess what? The actual upload limit is 15:59, because this is 15:02, and was accepted.
DISCLAIMER: Make sure your setup is not receivable (or not usable enough) to neighbors, as copyright violations may occurr. This is intended for one household, so you got to play with it, to make it legal in many ways.
