Q: I have installed the signal booster but not really working? Any insights?
A: First, you must be in an area that has some signal in order for the booster to be able to increase the signal. It will not create a signal in an area that has none. If you have a signal, make sure all the lights are green. If not, you need more separation between the antennas. Also make sure the outside directional antenna is pointed at the nearest cellular tower for your service provider. You can find tower locations by doing a google search for your area. The outdoor antenna needs to be pointed in the general direction on the cell tower, and if you think you have that correct move the antenna up higher!
Q: Can this signal repeater work with multiple carriers at the same time?
A: Yes this signal repeater will work with multiple carriers at the same time as long as each one has some type of signal outside and they work on the same frequencies as the signal repeater.
