Share 1 antenna with 15 receivers - signal splitting in the shack with TV amp & multicoupler

I am often asked how I share the signal from 1 antenna to multiple SDRs (RTL-SDR v3 / NooElec NESDR SMArt, AirSpy R2 & SDRPlay RSP1A) and Scanners that run simultaneously in my shack. This video explains how I use a frugal $35 used Electroline TV Drop Amp in combination with a more expensive Commercial Strisdberg multicoupler to feed 15 radios from 1 antenna with no loss. If you need to split a signal across multiple Software Defined Radios, this is one way to do it. All my SDRs share 1 antenna. Links f
