USING EXTERNAL ANTENNA(S)
Typical single external antenna applications use only the XMIT/RECEIVE antenna connection. The second antenna
connection can be used when receive diversity is desired with dual external antennas.
ATTACH EXTERNAL N-TYPE SINGLE ANTENNA (OPTIONAL)
The receive-only internal antenna (left cable) should be removed when directional radiation patterns are
required for the external antenna application. Consult your appropriate engineering guide.
The external antenna mounting kit is an optional item that can be purchased from ADC
(LPS-299 L1). This kit is used when you are connecting an external antenna that has an N-Type connector.
Refer to Product Support on page 177. If the unit is not opened, refer to Open the Unit on page 20.
Step Action
1 Disconnect the right internal antenna (XMIT/RECEIVE) cable connections on both ends (Figure 6 on
page 23). Store in a safe place for later use. The left internal antenna (receive only) cable should be left
attached (refer to Note above for exception).
2 Remove the right rubber grommet at the bottom of the unit (Figure 7 on page 25).
3 Use a knife to slice a small cross or “x” between the four small round punchouts in the rubber grommet.
4 Route the external antenna lead end connector through the grommet and pull the cable assembly up
into the middle of the unit.
5 Seat the rubber grommet into the right grommet slot at the bottom of the unit (Figure 7 on page 25).
6 Connect the N-Type external antenna connector to the LPS-299 L1 SMA to N-Type adapter assembly
(Figure 7 on page 25).
7 Screw the SMA connector of the adapter assembly to the right side SMA connector of the LPS-20x
(Figure 7 on page 25).
8 Tie wrap connectors to the electronics cover with those supplied in the mounting kit.
