I purchased the unit with 2 indoor antennas, The installation was only problematic du to my home configuration. Ultimately I spent about 6-7 hours to get fully working. Backstory....T-Mobile no longer provides Femtocell 4G LTE devices, which they graciously have been doing for a number of years. SO when the one I had, took a dump. I sprang for the Dual Wall Mounted Signal Booster kit KSP.The unit one installed is preforming well. I use Network Cell Info Lite, an android app, to measure signal levels before and after. Preinstallation we had no bars and readings of -130db so really NO signal. 5G did not make much of a dent in reception. We do have a metal roof and our location is in a valley, but there is an antenna within eyesight, with a metal warehouse between us. i have the antenna mast about 25' high which is my starting point. I did have to add coax and I would have liked to get a 50-60 foot continuous piece between the antenna and the amp. But low and behold we have 4 bars and 5g service now.It is important,, that cell towers may be in view but often times they are directional, and may NOT be aimed at your location. Be sure to consult the cell map to confirm the directionality of towers. They recommend Cellmapper.net choose your carrier and check the cell tower icons for where they are aimed. DO NOT EXPECT THEY ARE OMNIDIRECTIONAL.So far a good investment. t also helps our ATT family members as well.Good Luck
