The THOR H-THUNDER-4 is a HDMI Digital RF Encoder Modulator for Full HD up to 1080P that supports 4 HDMI inputs. The signal source can be from any STB, satellite receiver, closed-circuit television camera or antenna source and the output signal is designed to work with any TV or STB. It comes standard with multiple RF modulation standards built in to assure this device can work anywhere in the world in a plug and play format.
This unit is similar to Thor's popular H-1, 2 and 4 HDMI-QAM-IPLL product line, but it has some differences. It's less expensive and each program is modulated on its own frequency and has a CATV RF output only, no IPTV output.
