2. Determine the appropriate location in the road near the
manhole to install the antenna:
 Locate the antenna in the road no closer than 18 inches and
no further than 30 inches from the manhole in which the
monitor is installed.
 Choose a location that is as flat as possible with stable base
material.
 If possible, select a location where the antenna would
experience minimal direct impact from road traffic.
 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.
3. Mark the square for the antenna installation, and then mark
location to drill corbel hole 2.5 to 3 inches back from edge of
antenna hole.
4. Drill a hole from the marked corbel hole location in the road,
through the corbel, and into the manhole using the 5/8-inch by
36 hammer drill bit. This will serve as the channel for the
antenna cable running from the antenna to the monitor in the
manhole. Be careful to avoid any cables in the manhole, and
restart hole slightly to the right or left if mesh is encountered or
resistance occurs.
5. Cut a 5.5-inch long by 5.5-inch wide by 1.63-inch deep hole in
the road using the non-rotating demolition hammer (in the
hammer only mode) with the 2-inch spade bit. This will serve
as the installation location for the antenna. The corbel hole
should travel under the center of this hole.
6. Level the bottom of the hole using the demolition hammer with
a bushing tool.
7. Drill a hole from the center of the antenna hole to intersect with
the corbel hole using the 1.25-inch by 12-inch hammer drill bit.
