This antenna slightly improved the signal strength of my 4G LTE internet router at home compared to using just one router. This depends on your location and the strength of the signal you are getting from the cell tower. I had to try several attachment points before getting a permanent increase. Some stains start out better but then decrease to a worse strength. In addition to line of sight to cell towers, other factors must affect signal strength. (may be voodoo involved)
