So the questions are:
-Is the ground plane better to be square/ round/ or hexagon/ or some other
shape?
Why not eliminate the need for ground planes with
vertically polarized dipoles mounted to inside surfaces
of empannage?
https://tinyurl.com/y3w4hf8y
-If the diameter of the ground plane cannot be exactly a square and the same
dimension as indicated on the installation guide what is the problem(s) with
it being slightly to wide or slightly too narrow than spec, or if the
antenna is not installed in the exact center?
ditch the ground planes
-The book says the two antennae should be mounted at least two feet from
each other so what if they were installed closer.or even co-located on the
same ground plane?
Mount one on left side forward, the other
right side aft. Getting separation shouldn't
be a problem.
-What about mounting these masts near human body parts (ouch)?
-What about mounting these masts near other avionics or other electrical
equipment?
back in the tail?

Last step, if you're motivated, would be to swap the locations of the new
GFI and one of the older ones, and re-test.

| Subject: | Battery Contactor Location |
Im building a Rans S21 and the battery is located behind the seats in the baggage
area. As per standard practice I installed the contactor (relay) next to the
battery. But this places it right next to the header fuel tank. Although this
is an aluminum tank it still concerns me that I have a live electrical device
next to 6 gals of avgas. Am I being overly worried?

Alex, there's another simple process that will help
move planning and design for your project forward.
It's called a Load Analysis . . . an activity that
starts early on in the design of a TC aircraft.
It's simply an organized listing of every anticipated
electrical load. For our purposes, I've expanded the
data set to separate out load groups by the bus that
powers the group. I've added space to call out the
proposed size of circuit protection and the wire
size for the feeder.
There are examples of these studies in Excel on
my website at
https://tinyurl.com/9rt6ymn
browse through those and you'll get the idea.
You MIGHT want to do three load-sheets. One for
the main bus, endurance bus and battery bus.
Here's a blank form that helps put the thing
together.
https://tinyurl.com/7jqypwj
If you know some current draws, fill them in
but for now . . . just identify every electrical
demand and hypothesize how you'll get power
to each device.
Use a pencil and keep clean-rub eraser handy.
You may revise this thing several times. Alternatively,
do your own in Excel.
Later on, you'll want to consider filling the
columns as operating requirements for the various
flight conditions are defined.
Once the architecture and energy management
details are known, you'll be 90% of the way
there . . . all the rest is wires, terminals,
crimp tools and string ties.

Yeah... no. I'm not that motivated. LOL.
I used a short extension cord this afternoon (instead of the long one with
a droplight that I used for testing yesterday. The smoker is working fine
and the four trout are looking finer!
My guess is that the smoker's cord is stiffer than the extension cords so,
when I shut the weather cover on the outlet, the cord is putting some
mechanical stress on the outlet. Nothing else makes any sense to me.
Cheers,

Radiation
Don't forget that while a homebrew ELT antenna may work better than the
supplied version, it probably isn't legal. Unlike most radio stuff, the
antenna is usually part of the certification of the ELT, and ELTs must be
certificated in the USA; even in homebuilts.
Won't matter until that picky a/w inspector comes to sign off the plane, or
if you get past that, dealing with the Insurance company after you survive
a crash.

It gets even better. Your architecture and loads
documents are the foundation for expeditious
generation of a ship's wire book.
As an electron herder on the heavy iron, you'll
already have a reverence for the universal
language of schematics for describing the
ship's electrics.
Take a peek at the documents posted at:
https://tinyurl.com/yytrxofg
https://tinyurl.com/y23kjwu6
These are examples of how your architecture
drawing (road map) and loads analysis (table
of contents) become the first sheets to a
page-per-system wirebook that would make your
project easily understood, repaired or modified
in the future no matter what language was
spoken by the technician.
If you're a CAD driver that will import
.dwg files, 95% of the work on your projects
documents is already done. You can download
the AutoCAD files from my website for importing
appropriate pages into your own work.
