UHF 400-480mhz Digital Mobile Radio VHF 134-174MHz 2W 8Km Audio Transceiver Module

I am pleased with them. It was a good choice for our small application. It is a robust device even it has a cheap price. I will use them in our further applications when we should use remote control. Thank you for your support.

Great news! We successfully performed the installation of the two units and transmitted our 4-20mA signal with both antennae. Even the smaller antenna suffices to transmit the signal without any losses whatsoever. So you can understand that we are very happy :) .

I believe you and your products. Sunny is very responsible. The RF modules are really strong and stable. Engineer's suggestions are useful to me. The most important is module's program can updrade on-line by myself. For some special projects, they can customize according my requirements. Thank you for your support all the time.
