Based on the popular TM-RF HD, this is the latest 2017 version which now has built-in dB Level adjustment and includes many advanced menu options to configure your set up.

Any HDMI Source

Connect any HDMI device such as a Satellite Receiver, CCTV system, Blu-ray player, TV Box, etc and watch it in crystal clear Full HD 1080p over a coaxial RF system. You can also watch on many TVs using a passive splitter or an amplifier (explained below).

Can be used in existing RF systems

If you already have a Standard Definition RF distribution system but your source device is in High-Definition, just swap your existing RF modulator to this and watch in High-Definition 1080p Full HD on a DVB-T compatible TV. The cabling is exactly the same. *please note, TV must be 1080p Full HD or 4K UHD (HD Ready models are not compatible).

Minimal Delay

The fastest in the industry! Less than 0.8s delay from the HDMI device, making channel changes super fast. The quickest in the industry! Furthermore, if using for video only devices such as a CCTV system, this can be reduced to less than 0.5s making mouse movement extremely quick (please contact Technomate Support for further details).

Crystal Clear Picture Quality

1080p Full HD at its best, giving you the same picture quality as an HDMI cable.


Apart from the UK Channel 21-69 frequencies, the TM-RF HD is also compatible with all UHF international RF systems.

Connect Multiple Sources

Can also be cascaded with up to 35 TM-RF HD in one system so you can watch different devices on different TVs! Such as Satellite on TV1, another Satellite channel on TV2, CCTV on TV3, etc.

All settings are controlled via the onboard menu screen and buttons.

Installation Notes:

  • Splitting: a passive splitter can be used. Furthermore, mains powered amplifiers/splitters can also be used as well as bypass models which can send IR Infra-Red remote control signals so that you can control the source device via remote control at every TV.
  • This 2017 version does not need an attenuator. dB can be adjusted in the menus.
  • Lip Sync: the TM-RF HD has been tested with many devices such as Sky, Virgin, BT, Blu-ray Players, Playstation, Xbox and there are no issues. If you are having issues, please contact Technomate Support.
  • Compatibility: this only works on 1080p Full HD & 4K UHD TVs. If your TV is 720p HD Ready, it will not work directly however, you can use a Freeview HD box (DVB-T2 box) with the TM-RF HD to make it work on an HD Ready TV.
