Think carefully about higher frequency extenders if you have a weak signal. I had a weak signal and my service provider broadcasts at 1900 Mhz and 800 Mhz in my area. I assumed that the YX-500-PCS would work OK because the provider broadcasts at 1900 Mhz. Not so. The 1900 Mhz signal was not getting to my house because higher frequency signals are not as robust as low frequency signals. I exchanged the YX-500-PCS for the YX-500-CEL that operates in the 800 Mhz range, and the "CEL" version did an excellent job of solving my problem.
