Need some help....
My home has metal siding and its real difficult to get a signal inside my home. I want to put a external antenna for the AT&T modem. Its a USB308 by Sierra Wireless. Problem is I cant find out if I need a 850Mhz antenna or a 1900mhz antenna.
Can anyone help with this? I called AT&T and was on the phone for 38 minutes and they couldn't tell me. My Zip code is 34433 if that will help in anyway.
