NET Team
on the Job
Do you need training on communications
security (COMSEC) equipment?
The COMSEC new
equipment training
(NET) team can
help you get the
knowledge and skills
you’re looking for.
Courses are
taught by a
highly
trained
staff
of Department
of Army civilians
with many years
of combined
experience.
Does this
antenna
mount make
my base
matching unit
look
fat?
Put one lock washer on the
bolt. Next, put the ground strap
lug and the other lock washer
on the bolt.
Then screw the
bolt into the vehicle.
The two lock washers for the
vehicle connection have
gripping
teeth.
The teeth score the paint
on your vehicle and ensure good
metal-to-metal contact.
The ground
strap
also helps
equalize the
electrical
difference
between the
antenna and
the vehicle.
That’s for your
safety and the
equipment’s safety if
the antenna contacts
a power line, takes
a lightning strike
or is exposed to an
electro-magnetic
pulse.
So, make
sure you have
a ground
strap running
from the
AS-3900A/VRC
antenna base
matching
unit to the
vehicle.
And make
sure the
connections
are tight
and metal
to metal.

The NET
team can
travel
to your
unit’s
location
to train
you.
Or
you can attend
the training facility
at the CECOM
Communications
Security Logistics
