Default Added a few turns.....

I was running my dipole with a 6 turn, 2-5/8" dia rg8x coax choke
at the feed point. I got the following "dips" on my SWR meters:

2.330 mhz, 1:1
8.000 mhz 1.8:1
23.615 mhz 1.2:1

A message I got specified that at 6 turns (2.342 uH), I might want
to consider adding a few turns. I added 3, for a new inductance of
4.798 uH. Now I get the following "dips" in my SWR meters:

2.330 mhz, 1:1
8.040 mhz, 1.8:1
13.630 mhz, 1:1 new!
23.615 mhz, 1.2:1

I didn't add any coax to make the turns - I simply used the slack
in the line I had to wind the turns. I can't wind any more without
adding coax at this point..... I have 8-1/2' of rg8x between the
coil and my Z11 autotuner.

Anyone know what's going on here? FYI the antenna is a 153'2"
dipole wrapped closely around a brick building. The feedpoint
is on the third floor window, the ends are 1) chest height and
2) 10' high. Everything is very well grounded (covered here
before)......
