This thread kind of helps me understand what might be going on with my JetPack. I happened to currently be located in a very strong Verizon signal area. With no antenna connected my download speeds go as high as the upper 20's Mb/s and my upload speeds are around 15 Mb/s.
When I attach a single omnidirectional antenna on my car roof my download speeds go near 50 Mb/s but the upload speeds drop below 0.5 Mb/s. Maybe I'm beginning to get a handle on what MIMO is about. I don't happened to have another antenna with me, to connect to the second JetPack antenna port but look forward to seeing if that will increase the upload speed.
My ultimate goal is to use the JetPack to cut the cord with Charter, my home IP.
