[TowerTalk] Homebrew tower...

[john at kk9a.com]

Water pipe has no specified mechanical properties so I would be concerned
about the strength of the structure.

I have been to a number of islands in the Caribbean and corrosion of towers
and antennas is a big problem. Galvanized towers require regular painting to
protect them from the effects of the salt spray. Cuba is significantly
larger than any place I have visited so perhaps in the center of the island
corrosion may not be bad, but certainly near the sea it will be.  Painting
the tower after welding with either a zinc enriched paint or epoxy will
protect the base metal.  You may have to paint it every year or more often
if you are near the salt water.

Hello everybody !!!.

I am WORRY about TWO THINGS:

TOWER STRENGHT: Is strong enought the 3/4 inch water pipe and 5/16 bars for 
braces to replicate a Rohn 25G ??

CORROSION: Heat during welding destroy galvanized protection...i can not 
galvanized after welding...maybe some cold galvanizing is possible...I am
worry 
about corrosion...maybe painting inmediately after soldering minimize
corrosion.

I am listening (READING).

Thanks,
