[Towertalk] Tower - do they make these anymore

[Mark <ackster@pcsonline.com> (Mark Ackaway)]

This is a bit OT for HAM stuff, but it does concern towers.  I have
seen around town old towers that were once used for TV antenna and
maybe CB.  It was a triangle base with about 6" sides and was about
20' high  Inside this was a pole maybe 2" that could be craked up
about 15' higher than the base.  Most of these seem to be installed
with just on brace to the side of the house.

Does anyone know who made them?  Are they still available?

TIA
