Phase Stacking

To all 

Just put  up my Old Wilson SY-1 tribander (26 ft  boom),side mounted at 40
ft. Have a 4 el monobander 26 ft boom also at 82 ft. Now has any one phased a
tribander and a monobander ???? and if so, does both in phase and out of
phase as well as single top and single bottom worth the effort. Everyone I've
asked has been skeptical. The purpose is for SS 96.  This my be the toughest
year for QRP class Sweeps Stakes but Just have to get that #1 one time, not
just the top 10 but #1. I  Need the edge.

Please any info is helpful, I have all info on stacking an matching but if
some one has tried it and it does'nt work, I will not bother to try. The
turning radius will not allow for a mono 20m to be sidemounted. Plus I would
need to add a mono on 15m someplace. 2el on 40m and 2el phased 80 loops make
up the lowbands but just want to try the phase !!!.

     The term "NO CODE" in this case could apply to those new Hams who
obtained their licenses without utilizing CW... although here it refers to
a medical decision not to resuscitate someone should their breathing or
heart stops. This can happen, particularly to certain Amateurs, as they
consider the first type of Ham mentioned above.

      I can assure you they are not on the WRC committee, they declined
the invitation.  Believe that they fall under the "or something category"

      Yes. For the bleak among us, having the words "NO CODE" as a tattoo
across the chest where the resuscitative paddles are placed is important.
For the truly spiritually destitute among us who have given up all hope,
this tattoo is placed across the forehead. This serves to identify this
sub-section of the population... much as the nose and nipple rings can
help to identify the Pearl Jam consumers.

If I remember correctly NCJ had an article about stacking dissimilar yagis
and basically concluded that due to the physical differences in the element
spacings and that the elements on each antenna were not exactly veritcal
from corresponding element on the other antenna, that non-traditional (ie
not in or out of phase but rather some intermediate level) phasing would be
required to optimize the stack. However in your case with the similar boom
lengths and hopefull the same number of active elements and element spacing
it may well be worth a shot!   
If you have access to one of the antenna analysis programs it may well be
worth some time on the computer before putting it up.  Modeling of
tribanders usually consists of using the same element spacing and working
the element lengths to get what the perceived performance is for f/b and
gain, the monobander will fall out from the dimensions directly. 
Of course the easiest thing is to be sure of the polarity of the feedlines,
baluns etc. and just try it with a tee to feedlines of the same length. 
Don't worry about the match (since it will be off without a balun etc.) but
do some on the air checks for pattern sanity. 
Of course if you do decide to do it, put out a note on your results.

Concerning Heil "broken part" call them, tell them and they will
send the part...It sounds like the "screw" broke...mine did...just

 I fully agree with K4VUD. Bob Heil is a great guy. I had the opportunity of
listening to a short and brilliant remarks he made in the 1993 Dayton DX

The small brackets  can be ordered directly from Heil. You may get several
of them, two for yourself and the rest as gift. I did that and was very much
appreciated by my fellows members at the local DX Club. Almost everyone had
the brackets broken.

In 1980, I was living in Helsinki, and the day that my antenna system was to
be raised a good Nordic snow storm arrived. The very good Finn ham radio
amateurs gathering for help assured me that in those latitudes no antenna
raised without snow were good performers. Maybe that is one of the OH
secrets ( besides big rotating towers, stacked antennas and above all their
dedication and operating skills )
