My friend has a cozy (fibreglas construction) with an icom a200 (i think) tranceiver.
When he transmits the initial quality is good but if the transmission continues
for many seconds it degrades to the point of being unreadable. Is this
likely to be an antenna grounding issue, a factor related to it being a glass
plane or a fault with the radio? Any thoughts appreciated.

If you'll send me your coax fitting I'll install what ever
length of RG-400 you wish onto it and use the fitting
to craft a comic-book on the subject for posting on
my website.
I've been wanting to do this article but haven't had

Hmmm . . . Did you get the connectors and tool from different
sources? One of my suppliers was Jameco but they don't stock
the import connector I used to sell any more but they do
offer name-brand connectors. Suggest you try

I think the thrust of the article was about

if it has anything to do with local RF getting back
into the radio, a dummy load check will show this up.
Put this device on the transceiver's feedline.
http://www.aeroelectric.com/Pictures/Tools/DummyLoad.jpg
Listen on adjacent airplane or handheld while transmitting
on subject radio. If the problem goes away when the antenna
is out of the loop, then the investigation will focus
outside the radio.
Is this a new condition or has it existed since day-one?

Sam,
If your not real sure about the alternator, AND if you have not
hooked up the Van's unit and its in its original box, Van will take it
back and you can go to the "Plane Power" 60A unit that has a built in OV
protection module. I traded mine and the Plane Power alternator looks
real nice. I have not run it yet but this summer it will be flying. Bob
Nuckols has talked with the people at PP and is satisfied that the OV
unit will work as advertised. It trips the field current and the
alternator goes dead. That is what you want.

It could be that the SWR on the antenna is so high that the
transmitter is protecting itself by reducing power. I don't know
about the A200 but a lot of modern transmitters have that
feature. Make sure all connectors are good and that the coax isn't
shorted somewhere.

| Subject: | Fiberglass fuselage |
Luigi,
I will do the same with two of the EI bipole antennas. The word is
there is no affect from the fiberglass. Do not try the same with carbon
fibre which will block the signal. In fact, I have now seen a number of
aircraft with the antenna farm in the tail. I am building a Legacy FG
which will include two comm, one gs and one marker beacon in the tail.
That's the nice thing about fiberglass, you can always move it after
testing if necessary.

Call them and ask? If they don't provide it, there are products out
there with internal regulators that DO provide overload protection. Why
pack extra equipment? The only thing you will need after that is a
dashboard indicator. Perhaps Bob has a diagram for wiring an indicator
light from an alternator with built in OV protection.

If your tailcone has a diameter of around 31 inches, you can try the
Morris Com Loop antenna, which does not require a ground plane and is
a better antenna than the typical quarter wave

That switch is more likely to die with age than from
any sort of "overload" in this application. See:

Influence due to magnetic properties is not so strong
as conductivity, i.e. sheet resistance of the material
in question. For single, relatively thin conductors
like antenna elements, resistive losses of say stainless
steel versus copper can be easily measured but not
terribly significant in terms of overall performance
on airplanes (we talk line-of-sight and can tolerate
rather poor antenna performance).
For ground planes, you have an infinite number of
radials all operating in parallel such that effects
of sheet resistance variability for copper versus aluminum
versus stainless under the antenna would be exceedingly
difficult to measure in the lab.
I can't think of any reason that magnetic properties
of the material being considered would offer an effect
worth considering beyond that of it's heating losses due
to inability to perfectly conduct a current.

"I can't think of any reason that magnetic properties of the material

I was trying to beat up use, and putting something magnetic near remote
magnetometer for Dynon D10A was a passing thought.
When the extra turbulence on the right side of the aeroplane due to
P-Factor temporarily were to put a magnetic charge on the JB Weld, then
slip to landing took it off................. White elephant attack I know,
but I mentioned that if it is magnetic, I could not detect any force
change with a powerful magnet. I figured I would mention in case someone
had same thought that it mat interfere with compass/s

Van' sells the PlanePower 60-amp alternator for $375
60 amp Alternator and Kit w/OV protection
Part Number = ES ALTERNATOR DELUXE
Price = $375.00
Their standard 60-amp is $270
Complete Alternator Kit 60 AMP
Part Number = ES ALTERNATOR 60A KIT
Price = $270.00
Just return the one you have and upgrade for an additional $105 (I too
believed the PP unit was standard)

Bob said "Did you spot any errors in simple ideas...?"
Okay, now I see what you intended - should have paid more attention to
the
thread subject line.
Perusing the Kit Planes article once more, the information regarding th
e
correct size fuse or circuit breader for a 60-amp alternator doesnt sou
nd
like what I thought I learned in the 'Connection. The article says use
70
or 80 amps to "prevent nuisance tripping because alternator ratings are
minimum ratings." I believe nuisance tripping on my Z-13/8 based syste
m
with 40 amp alternator is handeled not by oversizing a fuse or breaker
on
the alternator B-lead, but by using a 5-amp breaker on the alternator
field. My B-lead is protected with a 40 amp ANL current limiter which
I
believe is the correct size for my alternator.
Im also bothered by the "minimum rating" part of the statement, as this
would seem to imply that the alternator could easily produce that curre
nt
for long periods of time. We are supposed to be operating at about 75%
of
the alternator rating, no?
Is this more on track, or do I get the booby prize and have to go back
and
read 'Connection yet again until it finally sinks in?
