The 915MHz Helium Signal Amplifier works as a receive pre-amplifier with RX and TX Boosting automatically. It is a good helper to optimize LORA network for helium miners. Specific working frequency for EU is 902-928MHz. Power can be supplied via power plug directly or using bias tee over the coax cable. A built in filters avoids inferences with out-of-band signals.
