Hi John,
If you are handy with a soldering iron and hacksaw you might look into this:
http://www.arrl.org/tis/info/pdf/0109031.pdf
It cost about $75US for the parts and will outperform just about
anything on the market. I built one and it was easy to assemble and
works very well compared to a 100ft long wire. I am feeding a Harris
RF-590A.
