Frankly, the concept of “wireless coaxial cable transmitters” seems dubious to me. I must admit that in light of my previous experiences, I've yet to encounter such devices.

What I mean by this is, there is no way to wirelessly broadcast the core signal being transmitted through a satellite or television cable. It needs to be decoded in a box first and the subsequent video signal can then be wirelessly transmitted.

There seem to be two reasons for this. In a lot of cases the signal is encrypted and a huge amount of bandwidth would be needed to transmit the signal.

In this article, we will walk you through the various approaches you can take to wirelessly transmit video feed in your home.

Option 1: Cable TV/Satellite Coax > Set Top Box > HDMI Transmitter > TV

As discussed, cable and satellite signals are typically encrypted, so they need to be fed into a set-top box before broadcasting wirelessly around your home via a transmitter.

In this scenario, we feed the TV cable into a set-top box, and then output the HDMI video feed to a HDMI transmitter. This communicates with a HDMI receiver which is the video input on your TV.

Something to be aware of with this approach is how signals from your remote control are relayed to the set-top box. A good system will have some type of IR passthrough to bounce the signal across—a line of sight may be needed.

Option 2: Media Device > RCA Coax Transmitter > TV

If your source box does not output HDMI, then the next option is to utilize an RCA coaxial transmitter. RCA is the 3-cable (red, yellow, white) feed which provides video and two-channel audio.

For this approach, your TV feed (cable or satellite) is plugged into your set top box which outputs the 3-cable RCA. This is plugged into an RCA coax transmitter which wirelessly sends the video feed to the receiver connected to your TV.

Infrared signals from your remote control need to be catered for via a relay.

Option 3: Antenna Coax > Digital Converter Box > HDMI Transmitter > TV

If your media source is not cable TV or satellite, but a digital antenna, then this option is for you! Here the cable from your external antenna is fed into a digital converter box. This essentially acts as a set top box. From there, you plug it into a HDMI transmitter which then relays video and audio to your TV.

You can utilize any of the HDMI transmitters discussed above. Below is a digital converter box which could work for you. However, make sure to check whether your local networks are supported before ordering.
