FEBON Wireless UHF DVB-T COFDM HDMI INPUT transmitter modulator (generator) BOX.


This  Wireless  UHF DVB-T  transmitter box can let hdmi soure become UHF  wireless singal.

TV that embedded DVB-T  tuner can receive the wireless singal .


 Why use UHF ??

Why not  2.4 G / 5.8G?



Two reason.


1. UHF  DVB-T is tv level broadcast sinagl.  Signal is stable.

The performance of  Wireless  is strongly better than 2.4G / 5.8 G .

 even if UHF  is thorugh the wall,  the sinal is still good!





2. UHF DVB-T is like FM radio. 


You do not always care about if you can receive.

FM siganl can be receive by thound of people at the same time.

UHF DVB-T is the same as FM radio . 

UHF DVB-T  signal can be received by thound of receiver when the receiver is within the range.
