Review on 📡 High Gain Magnetic Antenna - Compatible with AT&T Nighthawk, USB800, Velocity, Verizon Jetpack 8800L, 7730L & Other 4G / LTE Routers & Modems - Proxicast 8 dBi with TS9 Connectors by Curtis Castillo

I have a couple of these to use with my Netgear LB1120, Google Fi, T-Mobile network, LTE band 12. Without antennas I get about 2Mbps up and down . if i'm very lucky When they were installed, I didn't see much better at first. So I went into my garage, opened the door and ran some tests. It turns out that my garage door is the primary cause of interference, and that makes sense. With the garage door open and the antennas disconnected, I get a slight improvement, but it's still inconsistent. However, once I connect the antennas, I get fairly consistent speeds of 12-15Mbps down and 3-4Mbps up. It's enough to get some work done until my main ISP comes back when I need it. The signal levels displayed by my LTE modem don't change all that much, but the throughput I'm getting is much more consistent. Honestly, I'm not stopping to get decent LTE speeds. I will look for a more permanent, higher gain antenna but I will not be returning it.
