It’s the
Simple
Things!
Cables—
Cap the cables
and their connectors when
they’re
not
connected.
Otherwise, dirt clogs them
and you get poor connections
and faults. Caps also seal
out moisture that can cause
pins
to
corrode.
If
caps
have disappeared, tell your
repairman so he can order
more.
In
the
meantime,
cover the cables and their
connectors with plastic.
Check the shielding for the
radio frequency (RF) cable
connectors. If the shielding
petals are bent or cracked,
you get RF interference. Get
damaged cables replaced.
Vents
and
flters—
The
AN/
MPQ-53 has lots of electronics that
produce lots of heat. If the radar
can’t get enough cool, fresh air, those
electronics overheat and the radar
stops working.
Before powering up, make sure all
eight vents are open and clean. You
can clean them with your shop vac.
The two antenna ±lters and the
two A100 power panel ±lters are
often forgotten during PMCS. They
need to be checked at least monthly.
In an area with lots of blowing dirt
and sand, make that weekly. Clean
them if possible. If they’re too dirty,
replace them. It’s a good idea to keep
extra ±lters on hand. It can take a
long time to get replacements.

It’s the
Simple
Things!
the patriot’s an/mpq-53
radar is a sophisticated,
complex piece of equipment,
but often it needs just the
simplest things to keep it
radiating health.

ah,
you
do
take good
care of me.
I sure
appreciate
it!
when we take
care of you, we
know you’ll take
care of us.
