That's interesting Skipp. I'm searching. I did find a couple references to PIM/IMD problems and one about poor signal with this type antenna.
The latter caught my eye as I've been sitting here half thinking coverage with this single dipole I tossed up there *seems* to be as good as with the whole array. I can't be sure since I haven't been "out there" to really see for myself what it is doing. At this point it's just a funny feeling I keep getting. Might be nothing to it... I'd have to go drive around for half a day to be sure. I will keep digging for old posts on the subject...
