I have always under stood that the "real rf" length depends a lot of the 
resulting velocity factor, height above ground, and type of soil beneath 
the run.   Is the 500 foot length with 5 feet ABG not close enough to 
approximate a wavelength on 160?  My 500' near bogs on grass really work 
well...they survive a bit longer  without getting hooked up in the 
deer's horns at 5 feet or more. And for some reason that always happens 
2 hours into  a contest, right.
