Description of Mobile A/V transmission device
"YTMW"Mobile A/V transmission device includes mini-receiver and mini-transmitter.The mini-transmitter is high power output, with transmitting antenna, digital modulation and A/V digital compress functions.
Mobile A/V transmission device is designed with compact structure, light weight and portability.
Mobile A/V transmission device has the function of transmit one way video & 2 ways audio signal(1 way data transmission is optional).
Mobile A/V transmission device is the ability to collect and transmit high-quality image on the scene.
Mobile A/V transmission device supports transmission range up to 50KM under intervisibility conditions so you can use it to built up a high quality A/V communication system in solider-solier,solider- base,vehicle-vehicle, vehicle - ship platform.
