Dave, I found some info on DB212 cable lengths doing a Google search.
A website by WA1ZYX has a couple of pages on modifying the DB212 for 6 meters and also cable lengths/matching and spacing of the folded dipoles. No info on changing element spacing from tower leg. This could affect the pattern. Also found a 4 page article by Decibel Products titled DB212 Series. Good info on antenna patterns. BTW, I've got a NOS DB225 cut for 75.70 MHz. This is like a DB212 with a director. It's got all the measurements for spacing for director, etc so this probably will be critical. I was thinking of trying to extend the elements for 6 meters. Has anyone done this on a DB225? Ken WA6OSB
