resistant Diplexer, a minimum of 1m (3') from other cables and
electronic equipment.
2. Hold the Diplexer at the selected location and mark the position
of the four screw holes.
NOTE
: If the Diplexer will be mounted on a vertical surface,
face the cordgrip downward to avoid any possibility of water
seeping into the box.
3. At the marked locations, drill 3mm or 1/8" holes to a depth of
10mm (3/8").
Do not fasten the Diplexer in place at this time
.
