Never
clean the MX-6707 with a high
pressure hose. Likewise, watch your
aim when you clean the rest of your
vehicle. To clean the MX-6707, use a
damp cloth.

Make sure the steel reinforcing ring,
NSN 5985-01-012-5425, is in place.
It keeps water from getting into the
matching unit.

here's our
chance!
*
Torque the mounting bolts to 100
lb-in. Overtightening cracks the plastic
cover and lets in water.
*
Whenever you remove the antenna, put a cap on the
matching unit. Get the cap with NSN 5985-01-135-2307.
To put on or take off the cap, gently rock it in line with
the tang. Twisting it breaks the cap’s strap. Then the cap
disappears.
If you don’t have a cap, try one of these fixes until you
can get one:
*
Use an M203 grenade protective cup. Attach the cup to
the matching unit with some rope, such as an extra piece
of antenna tiedown rope.
*
Use an aerosol can cap. Fasten the cap to the matching
unit with a thin piece of wire.
*
In a pinch, use masking tape. But, don’t forget to get all the sticky stuff off
before you put the antenna back on. Use an eraser to wipe off the sticky residue.
oisture can sneak up on your
AS-1729 antenna’s MX-6707 match-
ing unit and put it out of commission
before you know it.
Here’s how to win the war on
moisture:
The matching unit stays out in all
kinds of weather while other antenna
parts are indoors, so it needs extra pro-
tection, like this:
*
Take out the drain screw at least quar-
terly to let out the water. Drain it more
often in wet weather or high humidity.
To make sure all the water drains,
stick a hollow swizzle stick, coffee stir-
rer or sleeving, such as NSN 5970-00-
729-2969, in the drain hole to release
the vacuum.
