Waterproof Outdoor 868MHz Extender
Designed For Helium Network.
How to choose the gain of RX and TX?
if you use 4 way splitter( 4miners or more),and long cable(about
10m),recommend RX=17 TX=10(default);
if you use 3 way splitter( 3miners ),and long cable(about
10m),recommend RX=17 TX=6;
if you use 2 way splitter( 2miners ),and long cable(about
10m),recommend RX=12 TX=3;
if you have only one miners ,and long cable(about
10m),recommend RX=10 TX=0;
For easy debugging, we recommend that you buy a attenuator, 3dB or 6dB.
