I agree with you n the use of a balun... An unbalanced dipole will work,
especially on a receiver, but with reduced efficiency. For the weight of a
modern balun ( a couple of ounces) its well worth the few dollars to
purchase.
For those out there that don't know balun comes form the two words
"balanced" and "Unbalanced" All 300Ohm twin lead like they used to use on
television antennas is balanced line, all Coax is unbalanced.... Dipoles,
as Bryan said are balanced arrays.
There are some composite aircraft that have various antennas cast into the
flight surfaces. Even in these aircraft they have to be very careful to
make sure there are no parasitic elements (Metal) close to the antenna that
could play havoc especially with transmitters.

Craig,
I'd recommend filling the tubing with sand (or kitty litter) and closing the ends
of the tube with tape before starting to bend it. This will minimize the tendency
for the tubing to collapse when you bend it.

My plane has a Dipole VOR/GS/Localizer Antenna, probably a Comant CI-157P. This
is mounted on the bottom of the fuselage just under where the rudder cables exit
the fuselage. See attached photo. The signal from this antenna can be shared
with multiple receivers by using an antenna coupler. The only wires going to
my rudder are for the white, rear position light.
Many RV's have similarly mounted a Dipole VOR/GS/Localizer Antenna.
(I also have a comm antenna and a GPS antenna on the turtle deck, a GPS antenna
on the top forward skin, the belly of N601RT has a cheap bent whip comm antenna
for my hand held, a marker beacon antenna, and my transponder antenna. My ELT
antenna is from a handheld radio and is mounted on the baggage shelf, just
behind the passenger seat. No flames please. Check the archives for discussions
about ELT antenna locations. I should have put both GPS antenna's under the
canopy, but didn't.)

| Subject: | Large format printer referral??? |
Hi guys,
I've got a some jpeg files that contain full-size layouts for all of the rear
wing ribs on an XL. My plan is to print these out and use some spray adhesive
to tack them to the wood I'll use as form blocks (as a lot of builders have done).
Here's the problem - printing those boys out!
Does anyone know a place where I might be able to email my files and have them
print out large format paper printouts? I live in a really remote place on the
Outer Banks of North Carolina, and if I can just have the images printed out
and shipped to me, it'll save me several hours drive time and expense.
Even if there's a good printer in your town that is familiar with the job, I'd
appreciate a phone number or website address. Thanks guys. Keep drillin'.

The CAD program I use (AutoSketch) will print an arbitrarily large drawing
across many 8.5 by 11 inch pieces of paper with alignment targets at each
corner. Then I line them up, tape them together and use that. This worked
fine for my luggage shelf bulkhead. You might try this with one of the free
2D CAD programs available for download. Also with a CAD file many shops can
also plot it on a large-format plotter.
You may have trouble getting a jpeg printed with the correct dimensions.
Unlike a CAD file there is not much in the way of accurate dimensions in a
jpeg - usually just some default dots-per-inch figure like 72 DPI.

Thanks Ben. Somehow I was expecting you to have higher speeds. You are right that
the drag increases that much more with speed. Seems like there should be a
lot of drag clean up for the 701/801 that could be easily accomplished.

The 801` appears to suffer from the same fate as all the 601's. ZAC claims 10-15
mph higher cruise speeds then anybody seems to be able to derive. I can get
108 maybe in level flight and full throttle. That is using about 330 sea level
HP. Up here at 7000+msl that relates to somewhere in the 270 range. Keep in
mind the motor is VERY detuned to prevent the plane from making the lead story
on the evening news. <G> The 801, and I am guessing the 701 too is VERY areodynamicly
dirty so drag compounds at the higher speeds. For instance, on takeoff
I am burning 16+ GPH, at cruise at 50% power I can run 88 mph@ 5.9-6.3 GPH,
Speed up just 8 mph to 95 and the thing burns 11+. I will trade that off by just
leaving a few minutes earlier and running at the slower speed. With that all
said I still LOVE my 801..

You are right on about the over bend. What I did was draw the hoop out on a big
sheet of paper, lay it on my table, then bent the pipe to match. If you are
real careful and go slow you can get it pretty close. I had four hoops to
bend and got better results when I used a pipe bender from Harbor freight but
it is really overkill. This thing:
http://www.cooknwithgas.com/6_13_06_Canopy_Hoop_Bending2.JPG
It did, however limit the amount of "crimping" caused by the form that I got on
the first two I bent.
You are also right on about starting with a longer pipe. Take it slow and you
will get good results.

Hi Craig,
You'll probably want to bend the bows more than you're going to get from
a simple former because of the bend-back
that the aluminum has. As mentioned, fill the tube tight with blasting
sand or any fine sand. Plug the ends with wood
and use your form. The side radii are most crucial to getting the skins
to wrap around fully to match the vertical of the side skins.
Do pay attention to that. Also, I devised a bender arrangement with
casters on a table that will allow you to get the exact bend you want.
You have to ink the shape you need on the table and then use it or the
form to see where the bend is going. This can be very accurate. The
radius in the bottom 10-inches each side is very important as you can
see in the link provided because the longeron is curving as your bows
are coming down to meet the side skins. I've seen too many that seem to
just have a bend angle at the longeron for lack of enough bend radius to
match and curve at the same time. You can do it.
http://www.macsmachine.com/images/canopy/full/canopyframeup.gif
http://www.macsmachine.com/images/canopy/full/frontbowbend.gif
If you over-bend, the same clamps and casters arrangement can be used to
ease off the radius as well.
Good luck,

Just a little FYI about jpegs and printing. The 72 dpi Craig reffered to has to
do with resolution (clarity) not size. Jpeg size is measured in pixels. Think
of it this way...if you save a photo from your digital camera as 800X600 pixels
(not dots) and take it to any photo printer and ask for it to be printed full
size, it will always print the same size. If you send it as an email attachment
it will always display as 800X600 pixels. If you save that same photo at
different resolutions (72 dpi, 300 dpi. or whatever), the clarity, not the size,
goes up as the dpi goes up. Consider your home inkjet printer. Most have various
print quality setting you can select, such as 300dpi, 1200dpi, etc. These
settings have nothing to do with size. This can get confusing. Just remember...dpi
= clarity...pixels = dimensions. So, you see, jpegs have very accurate
dimensions right down to the pixel level. I'm not trying to be "Mr. Know-it all".

Actually I was referring to the limitations of delivering engineering
drawings as jpegs. Attached is a jpeg of a circle. The jpeg is 640 by 400
pixels. What size should the circle be when it is printed? Unless some
assumption is made about pixels per inch it is impossible to say.
For the jpegs that come out of my cameras (as opposed to being drawn like
the rib templates were) the EXIF information in the files say:
X resolution: 72
Y resolution: 72
Resolution: inch
Is that resolution information useful? No - but it is in the jpeg.

One thing to keep in mind with graphic file formats: JPEG, BMP, TIFF
and the like are raster formats not a resolution independent format
like PostScript or PDF. When one draws a circle @ 72DPI or any other
DPI in a raster format any alteration to the physical size (blowing
it up or down) results in a direct pixel interpolation. This means
the pixel sizes are increased or decreased in order to give you the
size you want. The observable effect of this is a case of the "jaggies".
PostScript on the other hand is THE industry standard page definition
language used in the graphics industry. When one uses a graphics
application such as Adobe Illustrator which is a VECTOR art
application, the resulting Postscript code which is interpreted at
the printer results in a resolution independent output. In plain
English it means if you tell the Postscript printer to print a circle
of say 5" it will figure out where to put the pixels to get the best
output instead of the computer drawing a dot at this size and then
resizing the physical pixels if you make the circle bigger at a later
time. The result is always smooth lines and graphics regardless of
what size you originally drew it. PDF is the modern replacement for
PostScript that is making inroads in the printing industry.
So, if you want the best results for drawings and your intention is
to blow them up to actual size then you need to use a graphics
programs that is capable of vector drawing like Adobe Illustrator or
Corel Draw (real pros don't use it). Whether you chose postscript or
PDF as the graphics format does not matter, but they're where you
want to be.
I used Illustrator to do all my "2D CAD" stuff like my panel and
other parts I had to fabricate where I needed them printed at 100%
on 8.5" X 11" paper with registration marks. This way I could tape
them together to get an accurate layout as intended. For other stuff
I fire up SolidWorks and generate PDF files from that (like my new
prop extension).
Sorry about the long post but I thought I'd add my $.02 worth since
I'm an I.T. engineer that specializes in the graphic arts industry
with over 20 years of experience and the clarification might help
some of you understand there's more to life than JPEG and GIF files...

Yes, I agree completely with Craig that jpegs are not the most ideal format for
engineering drawings. I initially plotted my rib templates in AutoCad 2005. Unfortunately,
there were no printing shops in my home town that could print from
the .dwg files. They could, however, print from jpegs. Honestly, they came
out fine. Attached is a photo of my right wing skeleton with ribs made with jpeg
templates. Looks OK to me and my EAA Tech counselor. Well, we've thoroughly
beat this horse to death. I think I'll go out to the garage and actually do
some work on my airplane.

No problem Craig. I'll set it on the front porch and you can get it when you get
here at 4:00AM if you leave now and drive fast. I owe you anyway so you are
welcome to it.

Drive? I expect you to fly it over after you fly off your 40 hours.
But as usual Larry did it with a couple of rusty casters and a c-clamp. I
expect his paint job will be a work of art too. Some of us (like me) buy
tools and some of us build them.
