Figure 5 EUM3005 Switched-beam Diversity Antenna — Beam Patterns
The end user must position the switched-beam diversity antenna correctly to receive an
adequate signal level. The Radio LED on the EUM3005, described in
section 1.3.2 , EUM3005
Modem - External Indicators and Connectors, or the setup menu, described in Setup Menu on
page 11, can be used to help with the alignment. Since the switched-beam diversity antenna
has a good front-to-back ratio, it can be positioned to suppress interference from other
wireless devices at the end-user’s premises.
The EUM3005 is not approved to be used with any other antenna. For installations requiring
an outdoor antenna, the EUM3006 Integrated Outdoor Modem is recommended for its
superior performance and ease of installation.
The EUM3005 Active Diversity Indoor Antenna comes equipped with a 3 m RF cable and
connector. The connector is a proprietary WaveRider connector, which is mandated by the
FCC requirement that the connectors used in ISM band products that are not professionally
installed must be unique, or at least not readily available.
1.3.2 EUM3005 Modem - External Indicators and Connectors
The EUM3005 has 3 connectors on the back plate to connect the modem to the end-user’s
computer, the antenna and the power supply.
The EUM3005 also has 6 LEDs, three on the back plate and 3 on the front. Two of the back
plate LEDs, Ethernet Link and Signal Level, are repeated on the front, making it easier for the
user to see the status of the modem and its RF signal.
Figure 6 shows the layout of the EUM3005 Connectors and LEDs, while Table 1 , Table 2 , and
Table 3 explain what each LED means.
