And, ironically, Piper aircraft build a large number of 4130-framed
airplanes, and used TIG welding WITHOUT normalizing. There has yet to be

evidence of a manufacture-induced weld-stress fracture. Something to say

for quality jigging and professional welding....

---------------------------------------------
I have built 3 Pitts aircraft with chrome moly using a TIG welder and
never experienced any problems, even pulling as much as 8 postive and 6
negative G's for many years.  I don't know how this relates to an
antenna mast per se, but the stresses may be simliar.
