You were not clear on whether they are circular or linear. If they are linear mount them both vertical and use steel tubing. If they are circular you can still use steel tubing, just be careful where on the boom you attach it.
It's and age old debate :-)

In putting together my antenna,?? (144-432)I need something to use as a horizontal- cross? support boom. What would be the best length, and,? what would be the minimum length,,,? would 6? ft separation be OK?? To minimize problems, should I mount one beam horizontal, one vertical? Does it matter which one, is? which way?
I doubt I can find a fiberglas boom locally,,,? what else could I use?? or, where can I order a fiberglas boom?
