I have never seen a compromise spacing that worked across such a wide
frequency range. There are pattern problems even going from 10 to 20
meters, much less all the way to 40. As you know, I interlaced the
tribanders with and without 40M elements so the tribanders are spaced 30'
and the 40M spaced 60'. Works pretty well.

Subject: [TowerTalk] Stacking question
Greetings, TowerTalkians --
Let me pose a general hypothetical question; I'm going to ignore
takeoff angles for the moment (I don't know if this is possible with this
question - sorry).
Suppose I had two non-LP multi-band yagi antennas that covered 40
through 10M and was interested in contesting. In the overall scheme of
things,
is there a stacking distance that would allow the benefits of stacking with
a
minimum of compromises? For example, is 50 feet too far on 10M (and 15M?)
and
too close for 40M? Intuitively I think it would be better to have the
40-10M
antenna on the top of the tower and drop the 40M from the bottom antenna.
This
would probably simplify the whole scenario.
I don't have and am not fluent with any antenna modelling software so
I'm just trying to get a feeling for this proposed system. Any input
greatly
appreciated.
Cheers, Steve K7LXC
