Small Hdmi Receiver Is There A Device That Can Combine Either Scart, Composite, Or HDMI Signal To RF?

Is there a device that can combine either Scart, Composite, or HDMI signal to RF? - small hdmi receiver

I have a satellite receiver (Topfield 7710HDPVR) without RF in / out, one can not combine the RF signal into a cable with the rest of the tube around the house. Installation (RF IN, add the RF OUT signal) is typically found in video. However, there is an alternative (smaller!) Devices are available, which allows me to do this? Satellite receiver has SCART, composite, HDMI OUT.
