SG-HBD03 is a new design ultra miniature COFDM digital video audio modulator/demodulator  PCB from  Shenzhen  Safe Guard Co., Ltd. It has the unit design with radiation fin (can be took apart if not needed).The most prominent this board is of composite, AV, HDMI, and SDI video inputs/outputs, designed with 3 video ports, HDMI, SDI, and CVBS, which is perfect for analogue and digital cameras. What’s more, it designed with RS232 port for data simplex transmission. SG-HBD03 is suitable for line of sight and non-line of sight transmission.Increased range  may be achieved by selecting transmission mode,booster amplifiers and antenna type.
