Hello Community!

I am looking to do something that seems to me should be possible, but I have no idea of the best/proper equipment to use in order to do it.

Basically it is as simple is this, I have a travel trailer on a seasonal campground, and there are 3 tv's, each location of the tv has a coax hookup so that you can get channels over the antenna, or if you plug analog cable into one of the ports, you can watch cable across all TV's.

Well I use Plex, Amazon Video, and Dish Anywhere all the time, and the best way to watch all this stuff on a TV is by using an Apple TV. Yes I understand I could use smart TV's to individually access these streaming services, but specifically the Dish Network Anywhere app, the only way to get that full screen on a TV is to stream it on my phone, and phone mirror to an apple tv box.

Now I have the pain in the ass option, of unhooking the apple TV and moving around based on what TV I would be watching, but If I really wanted to do this, then I wouldn't need to be on this forum.

The only common point by these TV's is a coax port, and open airspace, I do not have the option to run cables all over the place.

My thought was this, you can get HD channels over the air on a coax cable, so obviously there is the ability to transmit 720/1080i quality from a coax cable. My thought is some sort of HDMI to RF converter, that basically runs the apple tv video to channel 3 or 4 at all times, on any tv that is tuned to it?

The only converter I have really seen is from radioshack, and considering it is not an item i can find hundreds of around, this makes me think that this may not be as easy as it sounds, I don't want to lose the HD quality from using a converter, but there must be one capable out there because obviously I can get HD quality from a roof antenna on coax.



Maybe something like this but not $500

Of course I'm open to other ideas that does not require running different wire from point to point, such as a wireless solution.
 
I haven't seen a cheap HD RF modulator.
It is possible to send HDMI over an RG6 RF cable.

I'm not sure whether you can split the coax output and use three receivers or you would need an HDMI distribution amp and multiple converters.
An HDMI wireless solution is also possible.
If you don't need to stream to all three TVs are the same time a Chromecast stick might work for you and three of them are pretty cheap.
You will have to do some price shopping to see which option makes more sense.

Maybe you should look into a different solution?

The one thing I thought of that would solve every issue you have and make your life 10x easier is by using a IP-KVM to distribute your signal to every tv.
