 An **SMA connector for an external antenna** was also added to the DRAMCO LoRaWAN shield. This was done by **removing** the `chip-antenna`, capacitors `C3` and `C4` and inductor `L1` and replacing it with an SMA connector directly connected to the signal pin of the *RN2483* module. This modification can be seen on the right on the right most picture above.
 
+To protect the PCB's from moisture and other contaminants, they were given 2 coats of `PLASTIK 70`.
