- It all Adds Up
er, the coupler can only be installed one way within the box
to keep the length of the antenna feed wire between the SG-
235 and the mounting base of the SG-303 whip as short as
possible).
3. Align the four holes in coupler mounting bracket with
the four holes in the QMS bottom. Now install the four suction
cup feet to the QMS box—the mounting screws inset in their
feet fit through both the box and coupler bracket holes.
Fasten each foot with an appropriate bolt.
4. Trim the length of feed wire from the antenna mount
so that it will reach the porcelain stand-off insulator on the
coupler through the polymer feed-through bushings with the
antenna base unlocked and swiveled in the rearward position
(farthest possible extension). Solder the terminal lug (sup-
plied) to the end of the antenna feed wire and then bolt it to
the porcelain stand-off insulator on the coupler —using only
minimal force. (Caution: the porcelain stand-off can
crack from excessive torque.)
5. Construct a 2- to 3-inch ground strap which will ground
the coupler unit to the QMS box (and vehicle body/chassis)
by soldering terminal lugs on each end of the strap. Next, bolt
one end of the jumper to the coupler, then the other end,
along with the long ground strap, to the QMS at the hole with
the bright exposed surface. Attach the two side plates to the
QMS box with their corresponding screws. The QMS unit is
now ready for positioning and attachment to the vehicle.
Using the QMS Suction Cups. The suction cups of the
mounting system set the QMS system apart from any other
HF mobile antenna system. The innovative decision to utilize
suction cups to mate the QMS box to the vehicle surface
stemmed from the several functions they perform:
