My 20/30M Dipole looks good from the street… NanoVNA H4

After a trip to the roof and getting my 20 and 30m dipoles (inv. vee) looking good in terms of wires hanging nicely and fairly tight. I had to go back and dig up my experiment #204 from March 2025 about how to measure SWR with the nano VNA H4. Unfortunately, I didn’t write down how to calibrated so I’ve added that in now July 5 of 2026 and I’m sharing it with you in case you’re going to give it a try your shack. 73, Bruce
