Sorry, I didn't give many details. My idea was basically for a
commercial band antenna that needs to cover a fairly wide range in the
5xx-4xx bands. I've had good performance using fairly large tubing for
wide bandwidth requirements on single element designs in the past, but
I've never attempted a multi element design using the same materials.
Lets say I'd be using 1 1/2" .065 aluminum tube. Testing would be
required to find the ideal length. Yes, I'm basically trying to see if
something along the lines of the web page plans posted above could be
utilized with a larger size tube. I just wasn't sure about how it
could be wired up. But looking at those plans, I think I see the way
it could be done. It would just take a lot of experimenting to get the
dimensions right.

Hi Dave

It reads as thouigh you want to increase the signal strength at the
horizon by building a colinear omniazimuth array of dipoles. That is not a
simple thing to do when the gain is high and the bandwidth is 25% of the
center frequency.
It is fairly simple to model the pattern any configuration you are
considering. If you are at all interested in developing capabbility in
antenna building, you can get alot of information with EZNEC.
There are lots of guys lurking in this group who can and will help you.
