Enclosure Selection and

Mounting Methods

This chapter will discuss the recommended methods for mounting the RFID

antennae and housing the system components.

9.1 Initial Considerations

• The device will operate outdoors, fully exposed to the elements. It is

expected to operate in these conditions for extended periods of time,

without maintenance.

• Wind will aﬀect the vertically positioned antennae if they are not

sturdily mounted.

• Rain and sea air will cause corrosion to any exposed metal components.

• Prolonged exposure to the sun causes many plastics to become brittle.

• Sealed, dark enclosures will heat up to high temperatures if exposed

to the sun. Such high temperatures may adversely aﬀect digital clo ck

circuits and resonant circuit tuning.

• The uplink module uses an internal antenna. Reception is poor if the

device is placed on the ground.
