Cable and Wire .
..
Your commo cable and field wire can run between shelters aNd switch-
boards ±
but they can't hide from killers waiting to do them in.
These signal carrierS are the weak link iN your commo chain. They're
outside, where just about everything bad can ²
and does ²
happeN to
them. Careless operators aNd comBat boots; truck tires and taNk tracks;
camouflage paint and cloudbursts are all enemies of the common commo
caBle.
³ince cable can't hide when one oF
these killers comes around, it's up to
you to do the protecting.
MAKE CO´´ECTIO´³ COU´T
by looking for the guides (keys and
keyways) on connectors and recepµ
tacles. Match them up before you
hook up the cable. IF guides are missµ
ing or broken,
replace
the
comµ
ponent.
Without a good g¶ide, connectors
can go on wroNg, damaging the con·
nector or receptacle. The long, slender
pins oN some coNnectors are easily
bent aNd broken by bad conne¸tions.
Make sure connectors have 0¹riNgs.
These rubber rings make sure you
get a snug, waterproof connection.
To make hookups even easieR, use a
