Using this configuration, only one antenna is required for both
transmit and receive. The duplexer is mounted to the station top
panel and has a single N-type connector for the antenna. An N-to-
UHF adapter is provided.
Separate RX and TX
Connectors
In order to use two antennas, first disconnect the duplexer (if
equipped). Connect the Rx antenna to the UHF connector labeled
“RX” on the top panel, and the Tx antenna to the UHF connector
labeled “TX” (Figure 2).
Duplexer The duplexer allows the PDR 3500 to use a single antenna for both
transmit and receive.
1. Connect the UHF connector labeled “RX” on the station top
panel, to the N-type connector labeled “RX” on the duplexer.
2. Connect the top panel UHF connector, labeled “TX,” to the N-
type connector labeled “TX” on the duplexer .
3. Connect the antenna UHF-type connector to the connector
labeled “ANT” on the duplexer.
NOTE: To assure optimal performance and that human
exposure to radio frequency electromagnetic energy
is within guidelines, the antenna should be mounted
as described in Section 2, Safety and General
Information, under Fixed Site Antennas.
