tell me how  much antenna degradation I can expect by being off by .18"?

I don't think the effect can be computed, as the principal effect will be on radiation
pattern, but intuitively a small effect for that error.  ATC needs you
to put out at least 70W; if your xponder does 250W-plus as many do, no problemo,
IMO.

Subject: AeroElectric-List: Panel Wiring Reference?
From: "darinh" <gerns25@netscape.net>


I am looking for some type of reference material that can help me understand the
science behind wiring my avionics, switches, etc. in my panel.  I am new to
the electronics game and must admit that the panel scares the hell out of me but
I want to learn.  I have the ability, just not the know how.  What is the best
reference out there and where can I get it?

Thanks,

Darin Hawkes
