HV-122 Full HD 2-Way Diversity Digital TV Receiver TV/1.2GHz/2.4GHz bands support For HAM and FPV

             

 

HV-122 is a 1080 Full HD diversity receiver box which receives and decodes DVB-T (ETSI EN 300 744) HD/SD terrestrial broadcast signals. It features the video output of HDMI and Composite (CVBS) for DVB-T.
HV-122 is designed with 2-way diversity antenna reception, which can enhance high mobility support and mitigate multi-path effect.
Besides remote controller, HV-122 can be configured and controlled thru its UART port by an external host.
HV-122 can decode the mux’ed UART data in received streams and output thru its local UART port.
Besides standard TV channel bandwidth (5/6/7/8MHz), HV-122 can tune 1/1.5/2/2.5/3/4 MHz bandwidth channels.
Depending on the model options, HV-122 supports standard TV-band (170-860MHz), 2.4G-band (2100~2550MHz), All-band (170~2700MHz)

  • *There is a saw filter in the RF front end. The saw filter limits the reception range but minimize ACI (adjacent channel interference)
  • **When the saw filter removed, full band range is supported but poorer ACI. The sensitivity is ~20dB less at 170~700MHz.
