Pete,
You can sandwich the copper tape between a couple of layers of fiberglass 
cloth, let them set up and then glue the rig in wherever you feel like. Bury 
the copper tape directly in the foam of your vertical or glue it directly onto 
your vertical stabilizer if it is already glassed and cover over with a layer 
of fiberglass cloth if you feel like fairing it in! The best way is to place it 
on your foam before you cover it with fiberglass to begin with.

I'm trying to duplicate Mark Langford's comm antenna installation using a arrow 
shaft to support the lower half of the dipole.

So far, all the local sporting goods stores and hobby shops only carry carbon 
fiber arrow shafts. Can they be used in lieu of fiberglass? Somewhere, I 
thought I read that carbon fiber would hamper transmission of any radio 
signal? 



I await responses from those with any info.



Thanks,

I'll add to the comment or two already made.

Yes, the KR is an "easy to fly" airplane if the pilot is competent in
an aircraft with the flying qualities of a KR.  That being light on
the controls and very maneuverable.

Building a KR and then expecting to get your pilot license in it is
not the route to go unless you can overcome some obstacles.

1. Your KR will need a 40 hour  test phase flown off before you can
carry a passenger. Who will do that?
2.  It will be difficult to find an instructor that will give
instruction in a home built / experimental.
3.  Will your KR , with two on board, have flying qualities suitable
for instruction?
4.  Will your KR have controls set up to be an acceptable trainer?
5.  Insurance? for flight training?

Your best route is build your KR and, when the project is nearing
completion, work on getting your license the normal route.  Find a
flying club or similar to cut cost of training.  Have someone
competent make the first several flights on the KR to insure it is
performing properly.  Get some time in a similar flying aircraft,
check yourself out in the KR, and finish flying off the 40 hours.

The KR is not a "hard to fly" airplane.  In fact, I find it to be one
of the most enjoyable flying airplanes I've flown in 1300+ hours of
flight time.  Any "competent" pilot that knows and respects it's
flying qualities will have no trouble flying a KR.

Good luck..

Larry Flesner

If the "radar" is reflected off to another direction (ie, not back at
the radar station), the radar station won't "see" the airplane.  Note
the sharp and interesting angles on the F-117A, for example, which
"direct radar reflections in a few sharply defined directions"
.  Also, the
stealth aircraft have a special paint that helps to diffract and scatter
the radar signal so it has less of a chance to go back to the radar
station.  At least that's my limited knowledge of how it works, which
might be worth less than you paid for it.  :-)

I do know that carbon fiber does not allow antenna radio signals to
pass through it very easily, and will effectively degrade the signal so
badly that not much of the signal will get through, which is why we
don't want to put COMM or NAV antennas inside any carbon fiber structures.

Having said what I did about carbon fiber, some folks make the antennas 
themselves out of carbon tubing.  If you can get the right stuff that will 
allow a solidly conductive connection to the tube (aluminum spacer inside 
with a screw and terminal through the bottom, perhaps), that'd probably 
work, but I haven't tried it.  There are lots of links on the web where 
folks have done something similar.  It'd be worth a try, and would be even 
lighter and stronger than my setup.

KR>arrow shaft

I don't think I came up with that idea, I read it somewhere like Jim Wier's 
column or Bengelis or somewhere.  There are other ways to do it, but there's 
no doubt in my mind that it can't be done with any better combination of 
reliability and low weight as with hollow arrow shafting.   I got mine from 
Wicks, but  I checked Wicks and AS and apparently neither sells it 
anymore.  The last mention I see of it is in their 2007 catalog.  A web 
search didn't turn up the same stuff, but one option is 1/4" x .060 wall 
round tube at http://www.mgs4u.com/fiberglass-tube-rod.htm#pricelist .  It's 
heavier than mine (which is only.017" wall), but still lighter than wood and 
way lighter than solid fiberglass rod.  Google searches turn up a lot of 
fiberglass tubing used for RC model spars, so an RC model shop would be 
worth a call.  As for performance, as quickly as I threw mine together, I 
can hear or talk with no problem up to 150 miles away when I'm at altitude, 
and 175-200miles if it's relatively quiet on the frequency.  Joe Horton and 
I talk to each other all the time at 150-170 miles between us.

Carbon fiber is conductive, and attenuates or reflects radio waves. That's 
almost as bad as burying an antenna under aluminum.   It's often used as a 
reflector or dish.

Pete,
 Why not use a dowel rod with the copper tape covering it. You could also do 
as I did which was to use a piece if 1/8" x 1" poplar with the copper tape 
applied to it. If you just have to have a fiberglass shaft, go to the local 
sporting goods store and buy a fishing arrow. They are made of fiberglass 
because they are heavier and penetrate water better.

With my planes if you pull inside static it will only give you about 5 mph
