[Tower-Speak] Advice needed on dipole end "towers"

[chasm at texas.net]

I am wanting to put up a DX-CC or perhaps a Windom with maybe a slight rise at
its center to about 45'.  The ends will be at about 40'.
I have a 25G which I can run up to about 60' not to speak of any masts, etc.
to support the center or some point of the antenna.

For the end point anchors/supports of this dipole, I am looking at maybe using
chain link 1.5"od  fence tubing which is used to support the wire fabric.  in a
20' section, this stuff is virtually stiff as a (whoops!) well, a piece of oil
well drill stem<G>.

but, that is a 20' stick; I am not sure how to get another 20' attached and up
nor how stiff it would be  --  and may just have to settle for dropping it all
flat topped to 30'.  The problem is the typical subdivision small lot and not
wanting to get it or guys, etc into trees, other people's land, etc.  I can see
attaching a catenary support to the back side away from and along the axis of
the dipole to prevent any bend, etc.  Just seems to me that there ought to be a
book on "supporting tower structures" for dipole-end-points which would talk
about the rigidity and strength of so many products out there designed for other
uses but which could be adapted to ham purposes.  
Sign inspectors for municipal govts have architectural engineering books which
should cover all of this.

In fact.. just to ramble a minute, there ought to be a book for all sorts of
stuff which could be used - for antennas or grounding or whatever.

As an _OLD_ hat example, how about a brass door kick plate for a grounding
bulkhead for your shack's window?  etc...  I remember tip columns from ham
magazines from my youth back in the 40s and 50s which had all sorts of stuff
like this.  sigh  but that was when there was little to do with and necessity
really cranked up the imagination.

If anyone has any suggestions for a "guyless" 40' dipole anchor point, please
pitch in... off list is fine if you wish.

thanks in advance for any help
