ater can quickly shut down your AN/TPN-18/18A radar sets by blowing out
their electrical circuits. That includes the magnetron tube, NSN 5960-01-046-4482,
that is the heart of the radar system.
Waveguide dehydrators absorb
moisture, preventing corrosion and
shorts inside the waveguides. That’s
why it’s so important to eyeball the
color of the three wave-guide dehydra-
tors, NSN 4440-01-093-2831, during
your weekly PMCS. Blue is cool. If a
dehydrator is pink, change it. If your
-18A has a pink dehydrator, it’s NMC.
During wet or humid weather, check
the dehydrators daily. A new mag-
netron tube costs about $3,600. One
dehydrator goes for $10, so it only
costs $30 to replace all three of them.
