Meshtastic US-915 MHz and EU-868 MHz 5v Bidirectional RF Amplifier AB-89 Overview by Technology Master

Bidirectional Amplifier uses two amplifiers. One for Transmitter(TX) and other for the receiver(RX) side. It has automatic switching system to switch between RX and TX. In the HAM use the switching circuit needs power in the rages of 5W or up but TX sensing in this amplifier and other Meshtastic Amplifiers needs as little as a few dbm power. Watch my video to find out how much dbm exactly :)
