I'm currently in the job of getting the base antenna tuned with the use of my rig expert but after getting my brain all jammed up with the numbers I dug to find this. It made me realize that some of my understanding of the readings wasn't correct or I confused the hell out of myself.
I recently tuned a 6m Moxon beam using my RE-55 Zoom. The final results:
I honestly don't pay close attention to a super low SWR. I'm looking at being close to resonance at my chosen frequency and getting the L (inductive reactance) and C (capacitive reactance) numbers as low as possible. Everything else, SWR, RL (Return Loss, the higher the dB the better) will usually follow to a good place.
Not saying this is the only right way to tune but it works for me and lots of other folks. The chase for nothing but a super low SWR can ignore other important aspects than may not leave your antenna as efficient as it could be even though the SWR looks wonderful on a meter.
There are ham operators the world over talking long distances using antennas having a SWR well above 1.3:1. The reflected power differences between 1.3 and 1.9 to 2 are minute and cause zero issues with any decent transceiver.I wouldn't run any radio with anything more than a 1.3 SWR.
