I have a mixed pairs C3/C4XL setup at 30 ft spacing. Lower spacing would
have been better for 10M, and slightly lower (27 ft) looked best for 15M
gain/pattern smoothness when modeling, and one pair (the top) is spaced 40
ft for mechanical reasons (getting the big antenna right above a guy
point), but no problems in operation. It has only been up for a few
months, but it has done very well. I do not notice any problems on 10M,
even with the wide spacing. I see many instances (20% or more) when one
pair is better than "all". BTW, I feed the C4XLs stacked on 40M (60 ft
spacing) and am very pleased with the performance there. 73 John N5CQ

...My current plan, for whatever it's worth, is to install a C-4XL at 97
feet
-- building it now -- and stack a C-3 at 69. Since the 10-20 meter
sections are identical, that should give me good 10-40 meter performance.
I know Tom'll say I need a third C-3 down at 35 feet or so, but one thing
at a time!
