I was refering to the case where there is nothing to adjust the match and
getting something under 3:1 at the end of the feed line.

It was well within 1.5:1 within (part of) 10 and 12m bands.

Given an ATU, you can usually match anything and there is no need for the
physical complexity of a fan dipole.

Very true The ATU is only used for 15,17 and 20, but my (larger) doublet
with tuned feeders is better for 20 and 17, and about the same for 15.

I'm currently debating whether to add additional dipoles to the fan or
replace it with a smaller doublet (about a half wave on 20), which would be
about half the size of the existing doublet.

I may end up trying both, I doubt if there will be much difference apart from
a slight change in directivity.
