Jeff,

Your understanding is the same as mine, and your earlier post about vertical pattern is also right on. I'm simply observing the critical importance of soil quality on the gain (and vertical pattern) of vertical antennas.  At any given QTH, and for any given antenna farm, these are the things that are best learned from lots of A/B comparisons of antennas under different conditions. We know, for example, that paths exist at different vertical angles under different propagation conditions. The path to a given DX location may be low angle at one time and higher angle at another time.

73, Jim

Jim I don't think that Tim is saying the 4sq is 6 dB better than his beams.  I read that as a 4sq is around 6dB of gain on a model. Maybe I'm reading that wrong.  Pretty sure if it was 6 dB better than a set of tall stacks the entire world would be running 4sq on 40m and few would be using beams.
