[amsat-bb] Re: cross boom?

[Gary "Joe" Mayfield]

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 :-)

Subject: [amsat-bb] cross boom?

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?

thanks
