OK Jim,
I'll clarify. I'm a ham, I work as a radio tech (up to 7 Ghz). I've
bought and built one of your com radio kits...blah blah blah. You are
entitled to your opinions. I was just offering some ideas on what may
or may not have been going on. I don't work in the aircraft building
industry. I don't know how much silver is required on a production
aircraft...

You used to be a pretty fair guy. Now you seem to immediately attack
someone on their first post. You are really coming off as completely
arrogant. Yes, you're a big engineer (you are, aren't you?), you write
a monthly column in a magazine for homebuilders (who may or may not put
10 coats of silver on their fabric) and you don't listen to anything
from anyone who doesn't share your exact thoughts. I used to respect
you in the past, but now you seem just plain abusive (and abrasive). On
one of my posts on this thread you immediately took this attitude that
I'm a hick CBer who doesn't know anything (you make the claim without
knowing any facts about me...you just make those assumptions and attack)
I admit, I DON'T know it all like you seem to, but I DID measure
forward and reflected power with my Telewave wattmeter, my Icom A-22 and
the whip ELT antenna I used on my plane. The worst reflected power I
saw was 100-150 mW, which is no more than 10% reflected power of the
1.5W forward power (ie 2:1 SWR...not perfect, but acceptable to
military standards. I was an avionics comm tech in the USAF).

I think you could work on toning down your responses and state what you
find to be true without having to resort to name calling.

ExCUSE ME. I don't mind carrying on a technical discussion, but to suggest
that we didn't use standard manufacturing procedures OR that a certificated
airplane used "cheap silver" whatever the hell that is or spread it on a
micron in thickness and still expected to pass the inspector's muster is
just plain stupid.

Nor do you give me the credit for knowing how to take polar plots of
antennas to meet FAA expectations for certificated aircraft antenna
installations. You DO understand dB/relative angle plots, don't you?

Quite frankly, I think we have a self-anointed CB radio expert with us who
doesn't have a freakin' CLUE about aircraft antennas.

Good by, good buddy, 10-4?

OK, maybe so. BUT...I STILL vote for putting the antenna outside. Maybe
the wing was acting like a waveguide and the RF was coming out holes at
the root end Or maybe Bellance used cheap silver or only put on a
layer a micron in thickness
