HD portable repeater

MV2025SS2F8-AB-264

 

○ Outdoor rainproof chassis design

○ The panel displays the working frequency and other parameters, users can adjust it on site, intuitive and easy to use

○ Used as an independent transmitter and receiver

○ ABS data encryption processing

○ Adopt COFDM modulation technology and MPEG-4 / H264 image compression technology to ensure stable signal transmission and high-quality audio and video signals

○ The interface uses military waterproof socket, which can work with switching power supply

○ Use omnidirectional antenna to transmit signal

○ One video and two audio (left and right channels) signals can be input simultaneously

○ Audio left and right channels, stereo unbalanced input, support one-way voice signal output

 

○ Transmitter output power is adjustable

○ Dual antenna diversity receiving method using directional antenna and omnidirectional antenna to improve receiving sensitivity

○ 1.5 / 2/4/6/7 / 8MHz multiple bandwidth options

○ Dimensions (unit: mm)
