Review on Bingfu 4G LTE 8DBi Magnetic Base MIMO TS9 Antenna (2-Pack) Compatible With Verizon AT&Amp by Jason Maciel

I bought these for the Netgear LB1120 4G modem. I get 2-3 bands with no antennas so I was hoping to get 4-5 with them but instead I get 2. I literally turn off the antennas and get a different band. What? No antenna (internal antenna): RSRP: -108RSRQ: -17 If these two antennas are connected: RSRP: -109RSRQ: -18 No difference at best. In the worst case, they even break down the connection. Maybe it's my modem. I bought it used and these are the only antennas I've tried, but I'd be surprised.
