Author's Notes:
 I would first like to point out that I am an aluminum tubing pack rat.
 I have had enough antenna parts to build a set of three element yagis for 
ur
team on field day. Antenna tubing is fairly easy to come by if you take the
time to hunt it out. Many hams have tubing they are begging to get rid of.
 There are hams that become SKs and the widow would be more than happy to 
ave
you remove the antennas. There are beams that have taken a dive during a wind
storm or some that have been replaced because of bad traps or corrosion.
 Much of the tubing I have is old.
 It can be restored to near new condition with the wire wheel on a workbench
grinder. This is probably the single factor in which I was able to build this
LPDA for under $200. Tubing is expensive and prices vary from state to state.
 You can beat the system by scrounging the tubing and reconditioning it.
 The insulators can be procured from Telex/HY-GAIN at $15 each plus shipping.
 Anything else can be procured from True Value or Ace hardware. Use Stainless
 Steel hardware for everything you do.
 It's more expensive,but saves you in the long run.
