[TowerTalk] Copper wire prices

[Keith Dutson]

And now you can see why aluminum might not be such a bad alternative.
Prices on aluminum haven't gone up as much as for copper (in proportion).
Granted, it's a bit trickier to bond than copper (I don't think thermite
will work with aluminum like it does with copper <grin>).

Some may not realize what you are grinning about.  To illustrate, consider
the solid rocket boosters used on the space shuttle are fueled with a
mixture of ammonium perchlorate and powdered aluminum suspended in an epoxy
resin.

There is *speculation* that copper prices will fall next year, so you might
be able to do some options trading to get tomorrows price today (plus a
premium). (aluminum prices also fell yesterday)  But hey.. 
are we commodity speculators or antenna builders.

That speculation has a lot to do with reduction in troops in Iraq.  Right
now it's a crap shoot IMO.
