- Thread the outlet cover (ANT04) on to the upper assembly threads, twisting until moderately tight.
- Connect the antenna line (ANT13) SMA connector to the input connector of the preamp (RAD02).
- Finger tight should be fine, but if the clearance is too tight to get access, use an 8mm combination wrench to turn the connector.

- Place the ground plane assembly over the purple coupling section.
- Insert the purple coupling section into the upper assembly and press until snug.
- Loosen all four aerial retention screws on the aerial terminals (ANT07).
- Using a toothpick to push it through from the bottom, thread the conductive thread tail into the marked aerial terminal.
- Insert the aerial ends into opposing aerial terminals, taking care not to drop the ground lead from the ground plane.
- Tighten the aerial retention screws on the aerial terminals (ANT07).
