[Antennas] i want to build a 10 meter beam

Tue Jun 28 01:18:01 EDT 2005

I have a old boom from a beam ant...
about 15 ft long
i want to make a big 10 meter beam , starting with a 10 meter dipole, and 
making more elements,
to possibly fill up the whole 15 ft
But I don't know how to calc the element size and position ,
can any of the engineers on this mail group help?
i know it seems a bit , wild, but i wanna try it
Thanks
