THAT would do it for sure
would be almost impossible to interrogate the device with infinite (nearly) possiblities and learn what it is unless a very good guess
thanks for clearing that up
for sure this would protect the secrets

I have worked as an engineer for over 30 years. At one
company I worked at we would actually use sand paper
to take the nubers off of the important IC's in an
attempt to hide their identity. A 14 pin dip package
can be anything when it has no identifying numbers;
and the more umbers you remove from other IC's the
harder it is to reverse engineer.

Hi Dominique
There is no doubt that filling a circuit with epoxy
or hard wax would
resist copy artists., but if the Chineese REALLY ,
REALLY wanted to
copy one , don't you think they would get one and
sacrifice it knowing
that it wont go back together.(thats what the
Russian's used to do all
the time)
Even if it cost a couple of hundred dollars the
knowledge gained from
copying would be worth it.
Not only does filling withe epoxy , wax or hot melt
glue resist water
damage but it also is good at stabilizing the
inductance of any coils
that might be in there.

Hi Greg,
I have an ALA1530, an ALA100 and an AVA100, all
from Wellbrook.
Very fine antennas indeed.
Of course I have tried to open the units and see
the circuits ! Very
disappointing : the units are filled up with a
sort of hard black
wax which
makes impossible to see neither the components nor
the circuit. That
makes
of course the construction very safe for outdoor
use.
But I think it's also very safe for the industrial
secret !
Don't you think it's the main aim of the
constructor Andy IKIN to
prevent
any chinese imitation ?
Have a nice week end
