Two things that immediately come to mind are the matching methods used,
i.e., does it differ from one antenna to another and introduce a different
phase shift; and distance that the driven element is from the tower, i.e.,
is there is a big difference between the two antennas in this regard.  But
if your model includes these factors, then try it and see.  You could also
try building a "10M only" version of the C3E to put up there.

I finally decided to toss the old tribander and buy a C-3E.  I'm praying
that Tom gets it to me in time for SS SSB.  I'll have it at the top of the
mast at about 85'.

I was driving home tonight from dinner and realized that for the 10 meter
contest, I could throw together a 2 or 3 element 10 meter monobander and
mount it at the bottom of the mast, say 71'.  14' of separation isn't really
enough, but it will be worth modeling.

But - will it work?  I don't have a Stackmatch, so I'd have to feed them
with 1/4 wave phasing lines.  About all I really understand about stacking
is that it works much better with identical antennas :-)  Does anyone have
any thoughts on whether I can stack a beta matched 3 element monobander with
a C-3E in this manner and get it to work?  I'd appreciate any comments or

Thanks much,
