6-meters Indoors

As mentioned in my previous post, I was forced to bring my antennas indoors while our balcony was resurfaced, repainted, cleaned, etc. That was no problem for the 2-meter J-pole, which I simply had to adjust.

But my 6-meter dipole needed a new feed after being mounted.

That need prompted experimentation with autotransformers and loading coils, and while it did result in a usable antenna eventually, anytime I wanted to transmit, it caused my PC's keyboard and mouse to become unresponsive!

NanoVNA: SWR of 1.175 @ 51.02 MHz, 43.25-j3.27Ω
