[K3CAL] cross boom needed

[Bob Sheskin]

Thanks Ron. I am very thankful for the multiple responses to my request. I now have a piece of pipe to use and if I have problems with patterns I will look into plastic or fiberglass down the road. Right now I feel safer with the strength of aluminum hanging over the house.

Bob, are your beams rear or center mounted.  If you center mount them, you should use a non-metallic cross beam to reduce pattern interference.  If you use PVC, be sure to paint it to prevent sunlight degradation.  73,

I am looking for a piece of 2” aluminum tube to use as a cross boom for a 2M and 70CM beams I am stacking side by side on my tower. 4 feet is the length I am shooting for so if you have a piece you can part with let me know please.
