You've gotten some good suggestions about sources and materials. I
haven't seen anyone mention that if you choose aluminum, the stuff you
buy at a Lowes-type store is very different than the type normally used
for commercial Yagis. It's a lot softer and weaker. I don't have enough
experience myself to know if it's good enough for a 6 meter beam, but if
so, it'll be nowhere near as strong as something made from the proper
variety of aluminum (e.g. 6061-T6) which you can get from some of the
sources that have been mentioned. So don't use hardware-store aluminum
tubing for anything that requires much strength or durability.

Hi Group,

Where can I get some good grade material for a 6 meter beam elements?

Does a hardware store such as Lowes carry anything that would work for the
elements?

Beam size is 4 to 6 elements.
