[TowerTalk] Upside down mast

[Frank Donovan]

Hi Richard!
Yes, I tried it over 20 years ago, and it works fine.  Since that time
I've gone to a multi-tower station, so no need for those trix any more.
My lower mast had a large 20 meter monobander mounted on it.

Be sure you use masts with adequate strangth (especially the "regular"
mast thru the tower).  Just as in your drawing, I used two short
horizontal masts and lots of u-bolts to attach the lower mast to the
"regular" mast.
