to Walt:
Be sure to use silver solder when joining copper tubing. The lead solder
will lead to a higher joint resistance -- sometimes considerable -- and
somewhat reduce your resonant current. Lead solder will work but silver
solder is much better for this RF application. Any welding shop will
probably sell you a single stick for $1.50 or so.
