10. Apply a piece of white release tape onto the top of the antenna,
and then seat the antenna into the bottom of the hole. Once the
antenna is firmly seated, remove the release tape.
11. Apply the asphalt on top of the antenna element. When using
asphalt, scoop the warm material into the hole and then pound
it in using a hammer. Place a piece of wood or metal between
the asphalt and the hammer to prevent the hammer from
sticking to the asphalt. Make sure the asphalt protrudes slightly
above the level of the road surface.
12. Sprinkle a thick (approximately 1/8-inch) layer of sand over the
asphalt, and then pound the sand lightly into the surface. The
sand must be used to ensure the asphalt does not adhere to
objects, such as vehicle tires, while drying. ADS recommends
dusting the surface with sand once again before leaving the site.

13. Coil the slack antenna cable and secure it away from the other
cables in the manhole. Slack enables the technicians to remove
the monitor from the manhole for maintenance or service
activities with the antenna cable still connected. Do not bundle
the antenna and sensor cables together! This can significantly
diminish antenna and sensor signal strength, disrupting
communications and limiting sensor accuracy.
Note: To prevent signal loss and damage to the cable and
antenna, do not kink or bend the antenna cable when
coiling.
