Since analog television is offline in almost all countries, channels are now unoccupied and can be used for a short range broadcast. This might be useful for running your own household TV station or to test televisions wirelessly.
Broadcasting in your home requires three pieces:
- An RF signal source. This could be a device that outputs RF such as a NES or the output of a HDMI/composite-to-RF adapter.
- An RF amplifier. This is a simple device that takes the RF signal via coax input, amplifies it, and sends it to a coax output.
- A TV antenna. This can be a set of rabbit ears or any other TV antenna. In this case, we will use it to transmit rather than receive.
- Plug in power to all devices.
- Plug your RF source into the input of the RF amplifier.
- Plug your antenna into the output of the RF amplifier.
- Tune your TV to the channel that the RF source provides (usually channel 3 or 4).
