Chamber
Large (Deep)
Chamber
T-Bar
Fix to Logger top or
underside of atplas lid,
ensuring that the antenna is
as high in the chamber as
possible, 3-4 inches can
make a big difference in
signal strength on
underground assets.
T-Bar on logger
I Bar on chamber
wall
Try the T-Bar as per Atplas
instructions and I-Bar on
chamber wall
– use the best
performing antenna in the
position that yields highest
signal strength.
Carant on bracket
T-Bar on logger
I Bar on chamber wall
Try the Carant antenna
attached to a bracket facing
down
– do not fit this if the
chamber is likely to flood
regularily. Try T/I-Bar as per
Side/Hydrant chamber
Choose the appropriate antenna and position it within the chamber
Ensure antenna terminal is tightened and wrapped in self amalgamating tape to seal
Perform Signal test with chamber lid/door as close to closed as possible
Signal > 14
This is a sufficient signal
strength for good
communications
Signal 7-14
1) Try an alternate network
logger/SIM card
2) Try an alternate antenna
location
3) Try an alternate antenna
Use best antenna/location
combination.
Signal <7
1) Try alternate antennas /
positions as per 7-14
2) Try to locate an I-Bar
externally (above ground)
where considered safe to do
so.
3) Recommend site for
above ground Antenna
installation. Take supporting
photographs.
Complete GPRS test to confirm correct communication
Ensure antenna terminal is tightened to and wrapped in self amalgamating tape to seal
Phone office (if possible) to confirm data is arriving
