Does a knot in insulated 16g stranded wire pose a problem

operating 40-10m with a KAT2 autotuner. The knots are 1/2"
away from the feedpoint & lock the antenna to it's center
insulator.

HI Ken, the knot would pose no problem at hf frequencies. It would
pose even less a problem if you stripped the insulation off at the knot
and soldered it all together.
