How to add additional channel for analog TV (Local Community Channel)

[michaelm]

Hi all,

My name is michael. I am currently working in a project which is involving the broadcasting of a local community channel. My background is Computer Science engineer, and I somehow is not too good in this particular things. Hope any of you could give me an idea to solve this out.

So, the brief problem is like this :
There is a rural community that wants to make a local channel. The problem is that they are all using a same television, however they are not capable of getting any channel (from the main broadcast in the town) . So, they asked me to help them, setting up a local channel for their tv. However they do not want other village (other community) to watch their local channel (it is a matter of privacy they said).

The idea that came to my mind is that by adding a particular device (tapping?) on each of the villager's antenna, that acts as a specific receiver. And I also need an analog device to broadcast the channel to their antenna.

Does any of you have an idea, how to make an analog blackbox(or how to tap or what device that I could use) so that it acts as a local transmitter and receiver for the analog television (just for the local community, and the other community could not get the channel)?

Regards,


Michael

analog is dead in june in the USA
but there is low = power tv channels that have a very short range
basic idea is less power less range

there also was a lower power coded system that was used
to have a cable like multi channel pay tv system
that used a dish type antenna and was basicly line of sight

problem is how far you want your signal to go and how much cost for a box
to decode it

Thank you for reaching out for help with your project. I can provide some suggestions for setting up a local community channel for analog TV. Here are some steps you can follow:

1. Determine the frequency and bandwidth: Before setting up a local channel, you need to determine the frequency and bandwidth that will be used for broadcasting. This will depend on the available frequencies in the area and the type of antenna being used by the villagers. It is important to choose a frequency that is not being used by any other nearby channels to avoid interference.

2. Install a transmitter: Once you have determined the frequency and bandwidth, you will need to install a transmitter at a central location in the village. This transmitter will be responsible for broadcasting the local channel to the villagers' antennas.

3. Use a directional antenna: To ensure that the local channel is only received by the villagers in the community, you can use a directional antenna for the transmitter. This will limit the signal to a specific direction and reduce the chances of it being picked up by other communities.

4. Install receivers at each household: As you mentioned, each household will need a receiver to pick up the local channel. You can install a small receiver or "blackbox" at each household, which will be connected to their existing antenna. This will allow them to receive the local channel without affecting their access to other channels.

5. Use encryption: To address the privacy concerns, you can use encryption on the local channel. This will require a special access code for the villagers to be able to tune in to the channel. This way, only those who have the code will be able to watch the local channel.

I hope these suggestions help you in setting up the local community channel for analog TV. It is important to consult with local regulations and obtain necessary permits before proceeding with the project. Good luck!
