TT:
I'm sure Tim is well-intentioned in his wanting to make available for
other Hams throughout the TT world ideas on fabricating towers from
locally-available materials. Not every society on the planet has the
resources and raw materials that are available to us U.S. Hams in nearly
every village, suburb and city. I think we U.S. hams often lose sight of
this simple fact of our economic system - we've got a lot of STUFF available
for purchase.
For the past three years I've been working on a telecom project in
Haiti, reputed to be the poorest country in the western hemisphere. On each
of my visits to this country I've been amazed by the resourcefulness of its
people. The Haitians are able to use available materials to build what
appear to be comfortable houses and utilitarian commercial buildings. I've
seen construction work crews there use numerous slender wooden poles to
shore up the curing concrete floors of their multi-storied buildings. I've
seen bucket brigades of men standing on ladders made of these same poles and
thin scraps of wood for rungs, handing up bucket after bucket of hand-mixed
cement to their co-workers on the floors above them. And I've seen Haitian
carpenters remove the nails from these ladders and supports and carefully
pound them straight again, for use on another building.
When I read the cautionary notes that my fellow American Hams send to
the TT many about following the rules and being safe, I applaud the writers'
conscientiousness. It certainly is better to be safe than sorry. But I
also remind myself that, for Hams of many other nationalities, buying
something factory-made may be out of the question, practically and
economically. In those cases, something homemade may be the only answer.
