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.
Summary of what you'll need
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.
The Actiontec ScreenBeam Wireless HD Transmitter & Receiver Kit can be mounted anywhere without any wires. As it replaces bulky HDMI cables with wireless transmission, you can stream full HD video directly from your cable.
- No need for hard wiring
- Operates on standard 802.11 5GHz
- No Wi-Fi required
Thanks to its powerful technology, the transmission can pass through floors, ceilings, walls and reach your TV or projector at a maximum distance of 150 feet. This device can automatically connect to satellite TV, Blu-Ray, cable TV, and every other gaming or media console.
As the Actiontec ScreenBeam Wireless HD Transmitter & Receiver Kit comes with pass-through infrared ports, and you can use your existing TV’s remote control with it.
The Nyrius Digital Wireless Transmitter allows users to wirelessly stream HD 1080p 3D video and surround-sound audio within a 100-feet range. This wireless HD Ttansmitter can connect with any Blu-ray player, gaming console, satellite TV, PC, Mac, laptop, and other devices.
- Great long-distance coverage of 100 feet
- Sends 3D HD video and digital audio HDTV wirelessly
- Comes with 2x 100-240v AC power adapters
It transmits powerful long-range signals of uncompressed high-quality audio and video. Moreover, it can penetrate any solid obstacle in its way as it comes with low latency. It also features an infrared remote extender that can be used to control your devices from your home.
The J-Tech Digital Wireless HDMI Extender is currently one of the most powerful HDMI extenders on the market. It can transmit signals within 200 feet or a 61m range with no signal drops.
- One receiver can connect to two receivers simultaneously.
- The transmitter has an HDMI loop out port to connect a local display.
- No cables between receiver and transmitter
Without any interference, you can connect the J-Tech Digital Wireless HDMI Extender with as many as 4 independent pairs of the same J-Tech transmitter. Users can now access the J-Tech Digital Wireless HDMI Extender to customize their SSIDs and other operating channels.
As the latency time is only 0.1–0.3 seconds, you will experience no drop or lag in playback. However, this HDMI transmitter doesn’t work well for PC gaming nor for real-time shooting.
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.
Unlike other HDMI transmitters, the Nyrius 4 Channel Wireless Transmitter can be connected to any of the 4 supported channel frequencies. You should match the channel buttons on the receiver and the transmitter so that both are on the same frequency.
- Can broadcast real-time audio, and video as far as 225 feet
- Comes with an infrared remote control
- The option of adding additional receiver units
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.
The Mediasonic ATSC Digital Converter Box can convert over-the-air ATSC digital signals into analog signals for your digital TV, projector, and PC. It also allows you to record TV shows via a USB 2.5″/3.5″ external hard drive. It is advised that you do not use USB flash drives for recording.

Unlike other digital converter boxes, the Mediasonic ATSC Digital Converter Box comes with a Parental Control function, and an EAS (Emergency Alert System).
Unfortunately, the Mediasonic ATSC Digital Converter Box is not compatible with Comcast, Time Warner Cable, DirecTV, and DISH Network.
Option 4: Digital Security Camera/DVR Coax > SDI / HDMI Converter > HDMI Transmitter > TV
If your source is not TV, but a security camera feed, then you have a few more options. For digital signals you can utilize an SDI/HDMI converter and then one of the HDMI transmitters from above.
The Ferrisa Micro Converter SDI to HDMI comes with automatic signal detection support. It can be used as an SDI repeater and extender with a re-clock function.
- Supports 720p video footage at 30–50 frames per second
- Robust SDI to HDMI converter
- Comes with 1 HDMI output, and 1 SDI loop output
Option 5: Analog Security Camera Coax > BNC/HDMI or RCA Converter > HDMI Transmitter > TV
If your security cameras are analog with coaxial cables, then SDI won’t work. You’ll need a BNC converter to either HDMI or RCA.
The E-SDS BNC to HDMI Converter is a powerful converter that transforms analog signals to HDMI signals. This cable only works with analog cameras. It can accurately and reliably detect PAL/NTSC_M/NTSC4.43/SECAM/PAL-M/PAL-N format signals.
