My thoughts were that the carbon tube would be the exact same length as the
copper tape required according to RST. I just thought since everyone says that
pretty much only carbon arrows are now available, besides aluminum arrows that
if they would work then OK. As I originally thought, on a KR t
I said it was pointless to debate this, but I'm going to debate AGAINST
myself. An analogy that makes carbon fiber less than attractive as
something to wrap an antenna around is this: If you had a 3' aluminum tube
from an old FM antenna and put a layer of shrink tubing around it to
insulate,

Given the experiment we conducted at work where the conductivity didn't
affect EMF, I can't see why Larry's idea of wrapping the copper foil around

Carbon fiber is resistive, thus it would absorb energy and dissipate it
in the form of heat. It would likely be a negligible loss, but thats
what it would do. In the ARRL Antenna handbook (considered a BIBLE on
the subject of antennas) there is NO discussion of making an antenna in
this manner
General comment on the thread:
Aren't radio suppressed ignition wires carbon fiber? Conductivity of pure
carbon isn't bad, it just needs to be really loaded up to do the deed. The
material is used extensively in resistors and varistors. I have used carbon
inks and related carbon based materials in

Being a ham radio operator, and a practitioner of the dark arts of antenna
design, I can't imagine why anyone would wish to bother with complicating
something as simple, reliable and effective as a quarter-wave whip or
half-wave dipole. Of all of the things you can spend time, energy, effort

After the previous questions concerning carbon and fiberglass arrow rods for
making com antennas and the mention of carbon fibre/graphite rods I began to
think more about it. My first inclination was, of course I wouldn't use carbon
but now I would like to have this one question answered.

Sorry guys with this email. I was asked for a picture of the silver wings I
make and was going to send the guy a picture. Lost the email (my big clumsy
fingers) If you are reading this please send me the email again Sorry Warron
The canopy is very thin in the middle on top as it stretches while you blow
it. mine is not more than about 1.5mm. On the sides it is about 4mm.

Kr friend,
Kr friend,
Anybody out there who knows the thickness of there canopy.
I will maby start to make a new one.
Thanks stef
