Nature vs VSWR – Fight! Yar, unfair I know. Just yesterday I had tensioned up the radiator, and I think the lowest was 1:1.12, and a few other dips were damn close to that. This morning I saw that the sag was back “Hmmm, what does it say now?” So the sag has mad my vswr a lil worse for wear. The scan range here is 3-15MHz. The 80M, 40M, 20M bands are indicated in blue. Time to retention!
If you are interested in nifty RF metrics, then a VNA is a great way to go. I’m using a NanoVNA. 55 clams isn’t too bad for a pocket sized RF lab!
