The product is not good, it is not suitable for anything
I've bought the 698-960MHz antenna. I live 4km away from the sole BTS in the area and get excellent signal. Gain reported by my Teltonika RUT950 4G router is 20db greater than the genuine stick antenna, on LTE band 20. I've shortened the coax cable and crimped an SMA connector though, in order to lower the attenuation. The coaxial cable looks like standard RG58 as the dielectric is not made of foam, and with white outer plastic jacket. In my opinion, this antenna is not suitable for outside use, as coaxial connection to the folded dipole is only covered with heat shrink tube. I've installed it in the attic. VSWR measurements with miniVNA Tiny: 2.8:1@700MHz / 1.6:1@788MHz / 1.7:1@790MHz / 1.5:1@860MHz Also seems to be usable on the 900MHz band with decent VSWR but made no measurements. Very fast delivery to France!
