That's 246 / Freq x Velocity Factor x 5 (odd quarter wavelength)

Calculated values rarely ever take all the variables into account.
Virtually all calculated values have to be adjusted, i.e. cut
and tried, to achieve the desired results. What SWR do you get
when you increase the length by one foot? What SWR do you get
when you decrease the length by one foot?

On a related issue, my lowest SWR went from a broad 1.6:1 to a
narrow 1.1:1 after it stopped raining. Was that the wet asphault shingles
effecting the ladder line or just the wet ladder line? If it's the shingles,
I could elevate the line but either way, my tuner handles it. Should I care?

Do you care? :-) It is a good idea to keep ladder-line a few
inches away from anything that might adversely affect it. That
includes wet asphalt shingles.
