George, I had the same experience- I wanted to put together a small portable demo system, however, as noted below, the studs holding the elements together corroded. Maybe, if you can find a few Stainless studs, you might get away with this. Brass and aluminum create an interaction and freeze together. Good Luck Dee, NB2F

One thing I noticed was that after a month in the elements / rain, the studs connecting the aluminum elements together had corroded pretty severely -- I think the aluminum didn't like all the rain, and I could barely get the elements apart. I've seen some reports of other hams using arrows fixed on rotors in dry environments (Arizona), but if you're going to leave them outside in the rain, you might need to take precautions to prevent corrosion of the element connectors. 73 de Dave KB5WIA http://kb5wia.blogspot.com On Fri, Jul 22, 2011 at 10:12 AM, George Henry <ka3...@att.net> wrote: > Anybody have any experience with the solid-element single-band yagis from > Arrow?
