PoRG (abbreviation for “Power over RG-cable”), a simple phantom power supply to power some device over antenna cable (e.g. a preamp, active antenna, coax switch, etc). I recently built an active antenna for Adrian PA0RDA, and since his tests were very successful he wanted to have his own PoRG. For me this was a nice opportunity to reinvent this little thing:A couple of years ago I built my first
- I included a built-in power supply, so no external power supply is needed anymore.
- The built-in power supply also prevents the PoRG from moving around your shack due to the forces of the connected cables.
- It has different connectors for hooking up the transceiver/receiver and antenna, making it more difficult to accidentally swap the cables, insert DC power into your radio and see smoke appearing through the vents of your rig.
