Figure 26 –Flange or Antenna Placement for Low Traffic Areas
• When installing in a high traffic area, Neptune recommends that the dome of the
flange or pit antenna be recessed in the pit lid as shown in the following
figure.
• Recessing the installation reduces the range of the pit antenna.

Although the R900 cellular endpoint has a cable already attached (2 feet or 6 feet),
some installations can require additional cable. In these cases, the maximum cable length
between the encoder register and the R900 cellular endpoint depends on the register's
manufacturer and model. For more information, see "Encoder Register Interface" on
page 3.
