Another NOOB

[FATKAT]

OK, so I ordered a Sirio Tornado tonight from DNJ Radio. That LMR Coax is some high dollar stuff! I don't know how long it will be until I get it installed. If I understand the adjustment is in the final tip install of the antenna. The question I have is on the instructions which do I choose for the CB frequencies. They are 26.965 to 27.405 so where on this chart will that fall?

Freq. (MHz) L (mm)
27.0 1120
27.185 1060
27.5 955
28.0 780
(10m band) 28.5 610
29.0 460
29.5 300
30.0 165

Well that did not work- The BOLD / Underline is the length in MM for the Freq. next to it.
