Introduction

This HD extender transmit long-distance over one coaxial. It can transmit signals with a maximum transmission
rate of 750 Mbps. This product use lossless shallow compression technology, which can effectively ensure the
signal transmission without distortion.

The radio frequency signal is based on the principle of broadcasting transmission, using different carriers, can
transmit 100 HD image signals on a single transmission cable. Point-to-point transmission does not need repeater,
and the transmission distance can be up to 300 meters (Distance may be affected by the cable quality and length).
It can use TV transmission branch, distributor, amplifier and other equipment to set up the transmission network,
perfectly solve the actual requirements of various high-definition transmission.

It can realize synchronous playing of 300 meters long distance video with more receivers over TV distributor,
200 meters coaxial can be connected from transmitter to distributor, and 100 meters coaxial can be connected
from receiver to distributor.
