Antennas
The Hydro-Logic
®
Flexi Logger 100 has an
internal antenna,
which under
normal conditions is the best choice.
There is also a connector for an external antenna which can be used in more
challenging signal conditions. The external antenna must be mounted outside of
all enclosures.
Examples of conditions that may require an external antenna:
•
Installing the logger in a metal enclosure, kiosk or cabinet.
•
Installation in remote sites with weak network coverage.
External antennas for metal enclosures
If the logger is inside a metal enclosure, a low-
profile “teacake” antenna (part no
PDA9100.3315
) is recommended, which mounts in a
25mm diameter
hole in the
top of the enclosure. It is secure and tamper resistant if mounted correctly.
