Good Bias T, worked fine for powering a RTL-SDR LNA.

It did provide 5VDC to my active outdoor GPS antenna (via 25 ft coax cable).However, I got RF feedback. The outdoor antenna was picking up RF leakage from the Bias Tee. The strong RF feedback made the signal too scrambled to be used.I put a SMA 50ohm termination load on the Bias Tee SMA output as a test.The GPS signals into the board must be really strong, for the leakage from the Bias Tee PCB, went back outside up the tower to the GPS Puck. (Active GPS antenna).It might have worked, if the coax to the GPS Puck allowed it to be placed 50+ feet away from the T-Beam Meshtastic Node I was trying to feed GPS signals.I will have to buy a Bias Tee inside a metal box to get proper RF shielding.I'll keep this one, for use with a low frequency application.

I bought this bias to to power an LNA in my SDR setup. It showed up quickly and does the job !
