## For a delhi, I'd start the 1st set of guy wires at the junction of the
4th and 5th sections. [38' level]
Those sections are 8' long, but you lose several inch's in overlap. Ii had
one up back in the1970's, guyed,
and 10 x sections + prop pitch/mast, stacked yagi's. Mine went sections
8-7-6- then 5S to the top.
Then guy it at top of sections 7-10-13. The very top guys should be a
bit below the top of the tower, so you
don't get ant's, coax etc, hung up in them. IE; guy it at 32-56-80-102
Use the delhi triangular brackets made
for guying, then you don't stress the legs. If any rivets are loose, punch
them out, and replace with 1/4-20
galvanized G-5 hardware. You will probably have to drill the rivet holes
out. The existing rivet holes are just
a hair less than 1/4" diam. I'd spray any drilled out rivet holes with
that galvanizing cold spray 1st, couple
of coats at least. Our local home depot carries it in big spray bombs....
and was better quality than the stuff I got
from the industrial supply store. It has a certain shelf life, so don't
get too much at one time. It has to be WELL
shaken up, before using, and all surfaces clean of rust, grease/gunk/debri
etc.
## If the tower is well weathered and old, like I suspect, I'd get a
gallon of the galvcon stuff...and paint the entire
tower with it, then it ends up a dull gray/non reflective. Or at least do
any sections that look flaky. Easier to do
all this on the ground..vs after the fact. Go easy on guy tension on
those towers. 5/32" / 3/16" is ample to guy
a delhi.
