I'm looking for some chrome molly tube to replace the structural steel I'm
using now.
I currently have 2 22-23 foot long pieces of 1 1/2 inch with 1/4 inch wall
butt welded together. Over the splice is a 24 foot length of 2" which just
nicely fits over the 1 1/2.
This is on a 97 foot ROHN 45-G.
There is a TH5 at 100 feet, mounted on the 2" pipe.
At 115 feet there is a 7-L 6-meter C3i Yagi mounted on the 1 1/2 pipe right
at the top of the 2".
At 130 feet is a pair of 12 L vertically polarized 2-meter yagis on a 14
foot cross boom.
There is a pair of 11 L vertically polarized 440 yagis inboard of the
2-meter yagis on the same boom.
When the winds hit 50 to 70 MPH the thing looks like a blue gill fly rod
that just tied into a Bass. I find it amazing the VHF and UHF antennas have
held together for two winters.
My thoughts are the Chrome molly tube would be more rigid, albeit a whale of
a lot more expensive.
Any thoughts? Socially acceptable suggestions?
Thanks
