Recommendations for 3/4G LTE Cell data Antennas, one of our Digital 1285PW's has been broken
I don't feel we're getting the best out of our AT&T LTE. The Pepwave generally only shows spikes of 4-5 Mbps and the range isn't very impressive.

check the bands your network provider uses and find an aerial that can receive signal in that range.

here is the one i got for my 4g router

Thanks, someone else mentioned a Poynting. I found this about frequencys. One A&T page (AT&T PREPAID℠ SIM Card Kit (Phone)) says "AT&T uses a GSM based network operating on the following frequencies/bands: 4G LTE – 700/ 850/ 1900/ 1700/ 2100/ 2300MHz Bands 2, 4, 5, 12, 17, 29, 30, 40, 66." However if 40 and 66 are truly active, I'd suspect at this point they have small footprints.
