3G Dongle with external antenna


Can someone recommend me a type of 3G dongle which supports external antenna and compatible with Peplink/Pepwave ?


Do you need a specific carrier? As far as what I know that works best, and is 3G ONLY vs being backwards compatible… Verizon = USB760. ATT = Shockwave. Sprint = MC760. In my experience we haven’t had issues with Peplink and these devices.
