so i decided im putting back up my HF antenna, doing it all new! I'm excited.

@freemo Cool!
In August I'm planning to put up a 2m/70cm J pole. I want to try measuring it with a NanoVNA to see whether it has low enough SWR to also be usable at 1.25m. I suspect not, but it seems worth checking.

@brouhaha SWR tells you nothing about its suitability for a particular frequency.. Remember a 50 ohm resistor is 1:1 SWR and a dipole fed with a ladder line is a good performer even at 10:1 SWR

@freemo @brouhaha the only thing SWR tells you is how well something is matched to 50ohms. There’s no information about radiating efficiency there.

@RFDave @brouhaha

Well its a bit more than that, but yea, SWR doesnt substitutde for radiation effiency
