Re: Metal vs. Fiberglass Boom



Tom,

     I only know of one real effort to study and measure the effects of the
metallic crossboom.  It was done by noted antenna guru wa5vjb, Kent Britain.
His results showed it can easily be situated to work as well as the
nonmetallic boom.  He presented this in a paper to the 11th AMSAT Symposium
(1993).  I purchased a copy of the proceedings from AMSAT.  The proceedings
is a good read, but I do not know if they are still available.  Kent has
given me permission to reproduce the paper.  If someone has the web space to
post the article I would be happy to provide them with images of the pages.

73,
Joe
