The antenna must be tuned to the frequency band of the service in use. Your 2014 uses an older Verizon 2G CDMA band. It's matched to that service. Unless you want Verizon 2G service, it's not going to work. I don't think Verizon would even provision you service to use that band anyways. They want to get GM and others off that band ASAP.
Wait. You're in Austin, and you have crappy cell service?!
