CiglowCiglow Amplifier Bias Tee, 25k -100MHz RF Wideband Amplifier Coaxial Feed Bias Tee for HAM Radio RTL SDR LNA.

I built a distribution amp, so I could feed the signal from my amplified magnetic loop antenna to three different shortwave receivers without having to switch cables. Rather than using an external t-bias that requires more cables and another power supply, I mounted this board inside my distribution amp, feeding it power from the 12v supply through a 5v regulator. I unsoldered the SMA output connector and wired it directly to the amp's input. It works fine for powering the antenna's preamp and even seems to lower the noise floor when compared with the original USB powered bias supply.I've ordered a few more of these boards, seems like a handy thing to have around.

I was not expecting this product to be so small and to have tiny connectors. They looked like SO-239 in the pictures but they are not even close. Other than that it works fine.
