Good news !!
And good initiative about the "Hall of Shame". It cannot be expected
that everybody has a reasonable understanding of radio wave
propagation. So, the illustrations of "How Not To" are very usefull.


Now the most important question: What about Brick delivery schedule
(for non-contest folks that often fly together in close proximity on
convergence lines) ?

It looks to me that we're about 6 weeks or more from delivery. *My
vendor
just sent out a note to his customers confirming which display they
were
ordering, but he hasn't asked for the up-front payment yet.

I've got a question. *It looks like the top of the glare shield is the
best spot.
However, in my plane (ASW-19) the glare shield ejects with the canopy.
If I ever have to bail out installing the antenna up there will keep
the canopy
from coming loose. *Is there some kind of breakaway connector I can
use in the antenna cable? *Alternately, is there a rubber duck kind of
antenna I can use instead that would poke through a hole in the glare
shield, like Bill Elliot did in this install:http://www.gliderpilot.org/FlarmInstallation

Thanks,

Matt,

I helped install many different FLARM units at Mifflin. On the AS and
LS planes we would attach the antenna from under the glare screen and
use Velcro or similar so that it would pull loose if you need to
eject. There should be no metal interference under the glare screen
like in a SH, so you can just put the top half of the antenna up
through the screen and have the wire just below. We did this on an
LS-6 and I believe it worked fine. The alternative is to cut a hole
large enough for the entire antenna to come through but still attach
it on the underside so it will pull loose.
