ATTACH EXTERNAL SMA-TYPE ANTENNA (OPTIONAL)
Figure 7. Attach N-Type and SMA-Type Single External Antennas
The external antenna mounting kit is an optional kit that can be purchased from ADC
(LPS-299 L1). This kit is used when you are connecting an SMA-Type external antenna only. 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 under Using External Antenna(s) on page 24 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 Screw the SMA connector of the external antenna to the right side SMA connector of the LPS-20x
(Figure 7 on page 25).
7 Tie wrap connectors to the electronics cover with those supplied in the mounting kit.
