We want to add a repeater for our house because we live in a 'dead' hollow. How do we figure out the frequency?
We have at&t and live between York and Harrisburg, PA along the I 83 corridor. Our house is in a hollow that loses signal strength, and with aluminum siding/steel roof, once inside we get nothing. Stopping at the at&t store and calling has not given us any sure answers as to what repeater (frequency) we would need to boost our signal. They are willing to sell us a device that works with our wifi, but if we try to leave the house while on the phone, it will drop the call. Can you help?
