I’ve tested mANT LTE 5o… that is disappointed me…
On our frequency LTE 800 that have VSWR around 1.27.
Maximum VSWR 1.06 i detected on international LTE bands “LTE 900” 
Brochure means “699 - 2690 MHz” and “360°” with 5dBi … without graph of Gain like in sxtr/lhgr.
That means this can give or not give some additional dB.
No one do any testing per Band 3/1/7 and 8/20 for EMEA of this antena with comparison with sxtr/lhgr - this means we don’t know how good/bad it is.
