Hi,

Does anyone know with high confidence what aluminum alloy the tubing in 
a OB1-4030 (purchased new in 2021) would be? DX Engineering could not 
help. WiMo has not yet responded.

I am trying to repair my storm damaged antenna. The only tubing I can 
find in the correct size is 6060. That seems very soft for antennas but 
given the appearance of the bend in the original maybe it was rather 
soft. I can get it at a very good price through September 30, so I am 
running out of time to find out whether this is suitable.

73,
Paul N1BUG
