All: Thanks for the replies regarding the mounting of 15 and 20 meter monobanders on a single mast. Although there might be exceptions, the general agreement seems to be that there is a slight detuni
I have one data point to contribute. From 1986 until 2000 I had a Cushcraft 20-4CD at 122 feet (one foot over the top plate on my Rohn 25 tower) and a Cushcraft 15-4CD five (5) feet above it, at 127
nope, multi-tower super stations just put up another tower. but before i got there i had 10/15/20m stacked the same way, just spread them out as far as i could on the 12' of mast above the tower. ju
My preference, as always, is to INVERT the Xmas-tree, with the 20m on top, 15m below it, and 10m below that. Used that arrangement for many years in the 1980's and early 90's. Don N8DE ______________
I have always been curious why someone would invert the stack. It seems that the mechanical disadvantage of the larger antenna on top of the mast would be more of a problem than any advantage. There
Well, it depends. I have a stack of sorts. A 40-2CD above a TH6 with 9 feet between the two. This puts the 40M beam a little higher (72ft). In this case, the 40-2CD is the smaller antenna in terms of
