The product did not work for me. For some reason, I always got a light sequence which was not listed in the manual. Not knowing what the sequence meant, I could not find the means to correct it. I called tech support several times, explaining the sequence and asking what it meant. They only told me to be sure there was sufficient height distance between the antenna and the base unit, which I did but to no avail. I was not impressed with tech support. For the amount of money the unit cost, I expected more help. Regardless, I tried everything the manual suggested and several ideas of my own, including taking the unit to a two story house several blocks away and installing it there. In every situation, the unit gave the same odd sequence. Perhaps it was just a faulty unit but it would have been nice if tech would have been able to tell me that. I finally returned it for a refund (that was good) but still have lousy cell phone reeception (that is bad).
