Vehicle mounted COFDM Video Transmitter with 20W Output Power Long Range Digital Transmitter
COFDM Digital Transmitter Feature:
Introduction:
This is a new arrival digital wireless video audio transmitter
which adopts the latest technologies of COFDM modulation and H.265
image compression that enables good NLOS (Non line-of -sight)
transmission with DVD quality video. The transmitter is compact
size with strong power amplifier for longer-range transmission.Good
heat resistant with three cooling fans. Be safety with
AES128/256bits. Work well in fast-moving transmission and
obstruction environment.
