today on signals everywhere we go over the basics of the bias tea and various STRs on the market and I'll teach you exactly how to enable it on the rtl-sdr v3 from the RTL - SDR comm blog and if you want to learn more about software-defined radio and radio communications in general be sure to subscribe and hit the bell icon so you don't miss anything a bias tea to put it simply allows you to send voltage up through your coaxial feed line to a device sitting right before your antenna but after the feed line itself in many cases this is an LNA or low noise amplifier used to increase the gain of a signal before it reaches your software-defined radio depending which software-defined radio you own the bias tee can be incredibly easy to enable in this case we're looking at an RSP duo paired up with the SDR uno software made by the SDR play team because this software was developed specifically
