Q: When I am home I have absolutely no service. it says extended. could the signal booster possibly work for me?

A: If you have service outside of your house such as on the street in front or back of your house then it will work if the booster is placed such that nothing is blocking it from the nearest tower for your service provider. If you have no service at all, even outside of your house, the booster will not work for you. In order to boost a signal it needs at least (a weak) signal to begin with. you need some type of signal outside your home to be able to boost it. If you have a weak signal outside and non-existent inside, the booster will work well and give you a good signal inside home no matter what construction material the house is.


Q: Can I use a 75 ohm cable to connect the signal booster with the antennas?
 

A: Yes, the signal booster can use the 75 ohm cable, but the attenuation is big. We recommend 50 ohm cable for the signal booster
for less gain loss and a better signal output
