 Avoid locations at which cars will remain parked over the
antenna for extended periods (hampering the signal
strength).
 Select a location that drains well so that water will not
collect over the antenna, blocking the signal.
 Choose a location that is as flat as possible with stable base
material.
 Select a location where the antenna will experience
minimal direct impact from road traffic, where possible.
 Make sure the location exists beyond the manhole’s iron
rim beneath the road surface. This will enable you to
access the manhole corbel when drilling the channel for the
antenna cable.
 Verify that no buried utility cables exist in the area in
which drilling will occur for the antenna installation.
Consider contacting a Underground Utility Locating
Service for assistance.
2. Mark the location for the antenna installation, and then mark
the location to drill the corbel hole 2.5 to 3 inches (64 to 76
mm) back from the edge of the antenna hole.
3. Drill a hole from the marked corbel hole location in the road,
through the corbel, and into the manhole using the ½-inch (13-
mm) by 36-inch (914-mm) hammer drill bit. This will serve as
the channel for the antenna cable extending from the antenna to
the monitor in the manhole. Be careful to avoid any cables in
the manhole, and restart the hole slightly to the right or left if
mesh is encountered or resistance occurs.
4. Cut a 6-inch (152-mm) long by 1.25-inch (32-mm) wide by
0.75-inch (19-mm) deep hole in the road using the non-rotating
demolition hammer (in the hammer only mode) with the
chisel/grinder. This will serve as the installation location for
the antenna. The corbel hole should be under the center of this
hole.
