That’s an equation that just about everyone in the electronics world strives to achieve: optimum power transfer! Power in equals power out.
But… from a slightly different angle: if that “power in” is the power that comes back in… then you have a problem. In this case: the reflected power.
Point in case:
After two Saturdays of troubleshooting this issue (I’m an essential worker nowadays) this old hound thinks it’s safe to say we have a problem up top. Because of recent heavy rain it could just be water in the balun or coax, as was the case with the 80 m dipole coax that I fixed last week.
For now our mighty, mighty beam has been disconnected and replaced by a multi-band Alpha Delta wire antenna, generously donated by WW5XX a while ago. (thanks James, you’re a visionary!).
Speaking of beam: there now is a 40 meter add-on available from the manufacturer. It comes in a kit, for those who want to have fun building. Wink wink, nudge nudge. π
That’s all, y’all. Stay safe. Stop picking your noses. You’re shoving the Covids up in there!
