My question is: what is an acceptable SWR range?
I am using a Kenwood TS-520 and an MFJ Versa Tuner II.

Your transceiver manual should specify a maximum SWR.
For my IC-706, it is 3:1. I consider anything below
2:1 to be perfectly safe. That's about 11% reflected
power. Most modern transceivers are equipped with
foldback circuitry to protect the finals.
