Antenna in cavity with patch
19. Tamp the compound surrounding and partially covering the
antenna in the hole until it is flush with the road surface, and
then sprinkle sand onto the compound surface to prevent the
material from adhering to vehicle tires.
20. Coil the slack antenna cable and secure it against the opposite
side of the manhole from the sensor cables. 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 damage to the cable and antenna, do not
kink or bend the antenna cable when coiling.
