SMA-RP / ANTENNA INSTALLATION: See Figures 6, 7, and 8.

5.2 The provided SMA-RP connector is
compatible with many consumer Wi-Fi style
antennas. But it must be modified before
installation.
As seen in figure 7, cut off the ground leg
that is on the top left side. This is needed
to prevent shorts to the module's nearby
circuitry (on some modules there is a tiny
SMD component hidden there). Also, the
SMA-RP's center post needs to be
shortened a small amount so that it does
not short out to the metal case, as shown.
Note: The four green dots in Figure 6 indicate the connector's ground pin
alignment area. It is important to accurately align the SMA-RP's center post
conductor over the top side of the module's RF input trace.
Important: When sliding the SMA-RP onto the assembly, please use care so that
you do not disturb the tiny SMD component that is on the RF input (of some
modules).
5.3
Carefully solder the three ground legs and the center post, as shown in Figure 7.
Ensure the module's metal enclosure is not shorted to the center post conductor.
Clean off ALL flux, even if no-clean solder was used. Perform a visual inspection
(do NOT use an ohmmeter).

The AWM680RX module's
antenna input port is shown in
Figure 6 (see red arrow). The RF
ground is the gold colored PCB
trace that is found on both sides of
the input (see green dots).
If you will be using Wi-Fi style
antennas, then go to step 5.2. If
you will be using our economy
PCB patch antenna (#AWM5.8-
ANT), then go to step 5.4.
