[TowerTalk] Carbon Fiber Tubing

[Rick Karlquist]

Before everyone falls in love with carbon fiber, look at this
chart (see URL below).  Carbon is only 10% stronger than plain
vanilla fiberglass (E-glass) and it's 25% less strong than
S-glass.  It is 3/4 of the weight of 'glass, big deal.
The only redeeming characteristic is *stiffness* (modulus).
Three times as stiff.  This is very useful in your golf club
or tennis racket.  For antennas, I would think it is only
important for Titanex style DXpedition type verticals.
