What’s my actual cell signal strength?
Product Description
This antenna mounts to the inside of an exterior window and sends and receives signal to and from cell towers. This kit includes a window mount with 3M® hook-and-loop double-sided adhesive tape for simple mounting to the window. This antenna stands upright on any flat surface, including windowsills, shelves, tables, countertops and sends amplified signal to cellular phones and devices in your home. Easily move the inside antenna to where you need better cellular reception or wall-mount it with a bracket and screws (included) or Command™ Strips or similar adhesives (purchased separately).
The Top Signal EDGE panel antenna mounts to an exterior window with the included mounting bracket. (Click to enlarge.)
This CEL-FI GO G41 cell phone signal booster system, available exclusively from Powerful Signal, is for for apartments, condos, and other inside spaces that need improved cellular reception but where installing an outdoor antenna on the roof is inconvenient or isn’t allowed by the building’s owner or HOA rules.
The GO G41 Apartment/Condo system can be set up in minutes. With one panel antenna mounted inside an exterior window and the other antenna pointed inside the living area, the GO G41 booster can provide hundreds of square feet or more of indoor cellular coverage. (See setup instructions, below.)
The CEL-FI GO G41 helps you stay connected and experience fewer dropped calls, undelivered texts, and missed email messages. Keep your data moving faster in areas with weak cell service and in buildings that block outside cell signal.
Command™ brand is a trademark of 3M.

Nextivity’s CEL-FI GO G41 receives the outside cell signal, amplifies it, and rebroadcasts it inside your house, apartment, condo, or small office. This allows you to stay connected in areas where cell service is poor or where building materials interfere with signals from the local cell tower.
The Nextivity CEL-FI GO G41 Smart Signal Booster system works with Verizon, AT&T, T‑Mobile, UScellular, and GCI Alaska 5G and 4G/LTE cellular bands. It does not work with other cellular networks.
The CEL-FI GO G41 Smart Signal Booster operates on two bands of cellular frequency simultaneously from a single carrier. It supports only one carrier at a time.
