Review on Enhance Connectivity with Proxicast 3G/4G/LTE Universal Wide Band Paddle Antenna (2 Pack) by Bill Wieser

Purchased for Verizon T2000. Without a connected antenna, the device shows 2 to 3 bars. After I put the antenna on the device and switched it off, it stayed at only 2 bars. I tried it for a week and found that it could actually affect reception because calls were going to my voicemail instead of getting through. I turned it off again, cycled it, and the device started working again between 2 and 3 bars. If you're looking to add this to the Verizon T2000, don't use this as it appears the T2000 can disable the internal antenna (which appears to offer better reception) and limit reception to the external antenna you are using. (I'm guessing it's like a manual mode guide. If you add an external antenna, you have to turn it on and then turn it back on [power cycle] for the device to recognize it.)
