some mast lengths are bad for cmc & some are good depending on if they are isolated or grounded,
I think Connor is interested in how the typical scaffold pole mast isolated on the side of a house effects the antenna pattern,

I avoid isolated masts that are close to odd 1/4wave multiples & go for something close to 1/2wave,

on the other hand if the mast is to be grounded i avoid mast lengths that are close to 1/2wave or multiples thereof including the ground wire & go with odd 1/4wave multiples.
