agreed... no disrespect to this guy but this is WAY too high (if 
the top is at 220' as the cover page shows). Had he placed it so 
the bottom antenna was at say 45 - 55' then it would have been a 
killer array... but as is it will not perform up to its 
potential a good share of the time. Radiation angle is the key - 
not gain (although having both works extremely well). When the 
angle is right however nothing should beat it for the most part.

g.
3 stack C31XR's at 121/81/41 where most of the time the three 
stack is better to noticeably better than any single antenna


Very impressive setup.  However, I wonder how effective it will 
be.  At that
height, I think the angle of radiation would be extremely low 
and as a result
be generally ineffective most of the time.  Yes, for very long 
haul and when
the band is closed it will be a killer, but my guess is that 
most of the time
it will be down from a simple two-stack at a modest height, 
since the useful
angles are not produced by the array.   I also know my upper 
stack on 10 at
135/165 stinks most of the time compared to the lower ones.  The 
upper stack at
200/150 on 20 lagsthe one at 100/50 lots of times too.

>From my experience with multi-level stacks, it would have been 
>a better
investment of time and money to put them in a vertical array and 
be able to switch
them in and out, as well as incorporate BIP/BOP.  And from an 
ease of
maintenance, construction and durability the vertical stack up 
the tower wins hands
down.  I also know my upper stack on 10 at 135/165 stinks most 
of the time
compared to the lower ones

But hey, it's his money and I'm sure the boys at STeppIR are 
very happy with
it.
