BUT, RX has two options
RX=12(default), RX=8.

How to choose the gain of Rx?

1、If there are fewer miners around you and you live in rural areas, we recommend that you choose products with RX = 12；

2、If there are many miners around you and you live in an urban area, we recommend that you use products with RX = 8；

3、If you want to buy another gain of RX (6-17dB), please contact us.

4、If your system uses attenuators or power dividers, we recommend that you use products with TX = 6.

This amplifier can only work with bias tee！
