Which country? Which model of TV? What year was it manufactured? VHF or UHF?
VCR, cable TV amplifiers, and an antenna.
Will work into the next room.
Look on ebay for link related.

yes, what you are looking for is called a rf modulator.
also can be found by looking up "composite to rf"
you simply disconnect the antenna from the tv and connect this device with a short cable to your tv and then cnnect whatever composite device of your choosing, or convert further to hdmi
>inb4 no i want to transmit over the air
this is illegal and you should not do this because you bight be caught and receive a big fine. The frequencies the tv uses are now in use by cell phones, and their respective service providers will notice your transmissions and will call the FCC to take care of you.
here's how to do that.
you want to buy what is called a antenna amplifier, or linear amplifier.
if possible look for one that has a lot of outputs like one that came out of a hotel or commercial building, those are much stronger.
these can be found on ebay usually.
you simply run a short coax from the rf modulator to this amplifier on the input side, and connect an antenna on the output side.
sounds good, thanks. i'll look into it. just want video on it so idc about over the air vs cables.
Sounds like bullshit. Surely there wouldn't be a problem if it were a low enough power transmission to only broadcast inside a house or room, much like how there are FM radio transmitters that can override real station broadcasts for ~3 meters with whatever you choose to pipe out.
FM broadcast radio is not regulated in the same way, and regardless, FCC Part 15 says that thou shalt not produce harmful interference. If granny next door can't pick up her favorite talk radio show because of your dongle, she is within her rights to get you cancelled.
It takes a license to broadcast in VHF TV frequencies, no matter the power.
Yeah, that's why you can buy a short-range FM transmitter in the store with no licensing or permits required, right?
Radio broadcast. Not TV.
the FCC allows you to transmit on the FM broadcast radio bands legally under a certain wattage with a CERTIFIED transmitter.
the FCC does not allow this on vhf bands, and the FCC does not allow ANY transmissions from any home built hardware or hardware used for an unintended purpose without either a license or a certified transmitter.
the fact that you just think well i can buy this thing from the store for my car and think its the same thing for any other frequencies is incredibly low IQ. what a fricking moron.
Yes! Also part of the certification for the transmitter I believe is that it has a fixed antenna so you cannot simply use a directional antenna or a booster. FRS (civilian walkie talkies) is like that.
>and the FCC does not allow ANY transmissions from any home built hardware or hardware used for an unintended purpose without either a license or a certified transmitter.
Part 15
you know what i fricking mean
obviously you can emit some RF but not in this context
Isn’t there an overlap of the top end of free to use marine VHF (174MHz) and channel 7 of a VHF tv? Afaik thats how pirate tv was done by some back then
No clue, but unlicensed frequency bands define not only the frequency but the mode too. Unless marine VHF allows broadcasting NTSC analog video on a 6 MHz, then you could, but you won't because you can't.
FM radio stations haven't given up their broadcast band to cell phones, analog television has. Low powered FM broadcasting is ok because it only impacts radio broadcasts in a very small area. Analog video broadcasting on legacy VHF/UHF channels disrupts cell phone service, which is a life safety issue. Due to the low power levels of cell phones, they're easily disrupted even with a weak interfering signal. Low power analog ended in 2021, though there were only a small handful of those stations left anyway.
Low powered digital tv broadcasts on frequencies allocated to digital tv would be a better comparison to consumer FM transmitters.
My understanding is that before amplification any RF Modulator within OPs budget is going to be putting out a few watts at most. Combine that with being inside his home and having a likely less than ideal antenna and I doubt anyone is gonna come knocking or ever notice, especially if it's not always on.
The channel he uses can affect this as well. E.g. the channels that fall on ham allocated frequencies are probably dead cause amateur television is pretty niche.
>a few watts
Considering a TV antenna receives a signal that's significantly less than a watt, i'd say that's being generous.
Inverse square law anon. If you are receiving 1/4W at two inches of distance, then it's halved to 1/8 at four inches, 1/16 at 8 inches... You can compare that to a rubber balloon, the membrane is pretty thick until you start inflating it. Eventually when the balloon gets very large, the membrane is so thin that you can see light through.
Now think of a 10000W transmitter that is 20 miles away.
TV Transmitter Kit will get you pretty far in der Googlizer.
Get you a blonder tongue agile modulator. Usually pretty cheap to find. You can use one to broadcast an analog signal for an older TV or receiver. Not sure why this one tard here is throwing a fit. You won't be broadcasting far enough to matter.
Does it have an external antenna input? You could wire the output from the RF modulator to the external antenna input and avoid the legal stuff.
Or wire a cable into the receiving end of the antenna chip inside the tv
