I’m thinking of a 2 stack of the M2 15M6DX. Both antennas would be mounted
across the face of Rohn 55 (rotating tower)... unfortunately their manual
doesn’t say what the distance is to the mast/balance point and it looks rather
close to D2. I asked the factory what the distance was and even though its been
in production for years – they basically said they didn’t know and didn’t have
a CAD drawing for it! Seems very odd to me ... so instead I’m here asking if
anyone has one of these up and if they know what the approximate distance is
from the balance point to the closest element?
I’m also considering a 40M4LLDD (although the comments by some about linear
loading tend to worry me – the reviews from those that are using it are all
positive – albeit without a direct A/B comparison we all know how relative it
all is) ... and was wondering if anyone has one of these close to either a 20
and/or a 15. I’m planning on ~12’ from the 20 to the 40 and ~31’ from the 40 to
the top 15... looking to see if there’s any interaction at all. I can move the
40 to a different tower with a bit more work IF indeed there is some
interaction noted.
Thanks to those that own one for their comments.
