And speaking of sailing, Tom, do you know what happened to Tom
Karnes who had a sailboat in SF bay and regularly took blind
folks on trips? 73, Jim WA6EKS

richard,
Actually there are several dingies designed for folks with no or
little
lower body movement. puff and sip controls for the sheets and
tiller and the
lot. Cost like sin though.

Tom, now that is funny - a sailboat for the disabled! LOL!
priceless indeed!
And, I think you are right on the painting matter too.

It might make sense to paint something expensive like the
Steppir with
"EXPENSIVE" marine paint, but PVC is pretty cheap it'd probably
be cheaper
to replace the pvc every couple years or so rather than use
marine paint on
it.
Anything "MaARINE" is way expensive. like anything for the
"DISABLED" Gosh,
think what they must charge for sailboats for the disabled!
Yeah, been there
seen that!
Just my not very humble opinion. <GRIN

as
much as regular outdoor paint would be.

Yeah, Kent, painting is widely recommended. Some sort of a
latex
paint is best I suppose especially since I will put the wire
inside
the PVC. I guess it will come down to the cost differential
between
1) "Schedule 40" UV resistant PVC versus 2) non-UV resistant PVC
plus
the cost of the necessary paint.

Hi,
Don't use the "black", that is not PVC but rather ABS. When the
sun
hits ABS it will bow due to it being black and the side of the
pipe
that is directly exposed to the sun will expand causing a bow.
PVC
that is gray is generally used as electrical conduit and offers
some
characteristic that greatly reduces static that might build up
in a
wire. Pretty much any PVC will work but I personally would
paint it.

Hi Tom!
thanks for this. Right - "Schedule 40" PVC it shall be!
Incidentally, is it grey? Someone said to use the "grey" PVC
for its
UV resistance; and another member of this list said to avoid the
"black" PVC for its carbon content.
As far as placement of the loop, I am planning just to place it
atop
my shack's roof. The roof is flat with a ~3% slant, and ~13'
high.

richard,
To clarify another post, you need to use "Schedule 40" pvc which
is U.V.
resistant.
I'd think each segment of your loop won't be much more than 2
meters long.
I'd kind of doubt you'll need reinforcemment for that
relatively
small setup, but you could also use a few extra rope supports
depending on how you're going to support the loop.
There shouldn't be any; issue with running the wire inside the
pipe,
except kind of a tangle while assembling everything on the long
wire.
How do you plan to support the loop?

Hi!
So, I am planning to make my RX only 10M (28.4 MHZ) full wave
loop
antenna into an octagon shape. My wire is insulated 14 gauge
stranded
copper wire.
I intend to use ~1.0" diameter PVC pipe for a frame. About PVC
pipe, does it matter if I 1) put the wire inside the pipe or 2)
tape
it to the outside of the pipe? I prefer putting the wire inside
the
pipe.
However, are ther= e any RF interference issues with PVC? Also,
I
wonder how PVC will hold-up t= o the elements - particularly UV
light (sunlight)?
