RF Modulators: Make your own Private Analog TV Channels the Easy Way. Modulators change a video signal to be usable on an RF channel. Normally modulators work on channels 3 or 4, but UHF modulators are also available to give more flexibility and avoid co-channel interference, as I run into in this video. It’s an easy way to play your own content on a closed-circuit TV channel available only to your televisions.

@bobskie321 9 ай бұрын

The video carrier of your RF modulator is AM instead of 8VSB that's why it interferes with the lower adjacent channel which means if your RF modulator is channel 3 it interferes with channel 2 as seen at 6:50 where channel 2 is missing. There are 8VSB RF modulators like those used in cable TV which do not interfere with the adjucent channel.

@NorthcoasterHobby 9 ай бұрын

You mean ATSC modulators? No doubt they work well with today’s digital TV signals, but they are pricey.

@NorthcoasterHobby 6 күн бұрын

Besides the modulator shown in this video, here is another modulator to look into that uses channels 14 and up. There aren’t any modulators to my knowledge that use VHF channels besides the ones that utilize channels 3/4. The only exception is a single channel modulator made by a company such as Blonder Tongue. A Channel Vision modulator like the one in the video below allows for multiple inputs and more than one output channel (selectable channel from 14-up).

Hey, quick question. What material are your radio shack modulators made of? I've been doing some research into finding a decently performant RF modulator, and I've been recommended to pick up an older radio shack one but I was told the metal ones work better than the plastic ones they produced later on. I found a couple of the ones you have on ebay but I'm not sure if those are the plastic ones or the metal ones that are being spoken of. Thanks in advance!

It is a wired connection, not wireless. It’s a modulator, not a transmitter. A modulator converts a line-level signal to an RF signal. The connection is made via coaxial cable between the modulator and the TV.

25 years ago not all TVs had a video input, if there's only an RF port then you'd need a modulator to convert AV onto a TV signal You can use these as a transmitter, but you'd need a booster to amplify the output
