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
our 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 have 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.
