Installation

The Network Unit (NU) should be placed where the existing cellular signal is best (generally by a window). The Coverage Unit (CU) should be placed in the location you need improved signal. You can optimize coverage by moving the CU. The NU and CU communicate with each other wirelessly to provide the best signal improvement possible. As the distance between the units is increased, the CU adjusts its coverage bubble to provide the ideal amount of coverage.

Mounting

Mounting brackets and hardware are provided to mount both (or either) the Coverage Unit and the Network Unit. The brackets come equipped with screws and inserts for mounting in standard drywall. The Network Unit has mounting holes on the back. The Coverage Unit has mounting holes on the bottom and on the back. The holes on the bottom of the Coverage Unit can be used for mounting the Coverage Unit to a ceiling.

Great quality wire for any automotive or 12 volt wiring
Size: 16 AWG-100 ft
This GS Power 16 gauge wire is excellent quality for any automotive wiring project. The copper is true OFC pure copper, not copper clad aluminum. It’s flexible, easy to route, and holds up well without the insulation feeling cheap or brittle. I have used it for automotive accessory wiring and some 12V equipment projects and it handled everything perfectly. The wire pulls cleanly, solders well, and the insulation thickness gives it a durable feel without being overly bulky. If you need dependable wire for automotive, marine, RV, audio, or general electrical projects, this is a great buy. I would absolutely purchase it again.
