i built my modem and router about 2 weeks ago and had this set of antennas on it (700-2700MHz 4dBi 4G LTE Omni-directional Antennas ) with this set up i was pulling in b2 b5 b12 and b30. it preformed all right so then i decided to put this antenna up ( 700-2700MHz WiFi 4G LTE 8dBi Directional MIMO Antenna (± 45°) now the only band i pull in is b30. im less than 2.5 miles from 2 different att towers and this is pretty typical results from speed test.

Can anyone point me in a direction to improve these stats?
Any help would be appreciated.
thanks

Here is a list of equipment i am using.

If the above stats is from the MIMO antenna, it is showing the primary as Band 30 (at 10 MHz of bandwidth) and the secondary band as 12 at 10MHz). These may or may not be the best bands to use at your location.

The signal stats look good although your RSRQ (quality of the signal) is a little low which may be a sign of interference.

Also notice the slight difference in the the RxM RSRP (-98) and the RxD RSRP (-105). We would like to see these numbers a little closer together.

At 2.5 miles from the tower, I would suggest adjusting the tilt on the antenna up a few degrees (5 to 10 degrees) while keeping an eye on the stats, and in particularly the RSRQ. I would also do the same for aiming the antenna directly at the tower. All adjustments should be in very small increments.

You might also try creating several different groups of bands, and try locking to a group and testing it.

While sometimes a pain, you will often find the best performance by trial and error.

Thank you it appears that I might be headed in the right direction. I appreciate your assessment and gonna start working on it this afternoon.
Thanks again
