[GreenKeys] OT. Antenna materials

Yes, although you may not have equipment capable of measuring the 
difference.  Current flows in the driven element, reflector and directors.  Steel 
music wire would be the worst choice.  Copper wire and bamboo would be better.  
Copper tubing the best.  Aluminum tubing is almost as good and is the usual 
choice because of weight and cost.
