Wrong Internal Antenna is Installed

Figure 3: Top views of the 3100 (RH-19) (left) and 2118 (RH-77) (right) antennas
The 2118 and 3100 antennas are similar in appearance. The important visual difference in
the antennas is that the slot pattern is very different. Also, the 2118 antenna is thicker
than the 3100 antenna and also has a spacer on its back side.
If the wrong antenna is installed, install the correct one.
