Verizon's 2G and 3G networks all operate on the dual-band frequencies. Any dual-band antenna amplifier will work. Verizon's 4G LTE network operates on the 700 MHZ frequency on Band 13. Do you need Verizon LTE data support? If yes, look for any 4G booster which is the LTE specific Wilson cellular signal booster.
To those of you who think it may be illegal to use cellular signal boosters, I can only say you don't understand the law. The FCC limits a person only by the amount of transmit power your device has. Yes it is true, you can only transmit at above 3W with a license, however if it were less than that, we would need one to operate our cell phones.
