The reason for the loss of the signal is the presence of a big mountain, as well as the connection of the rg59 cable with the combination of aluminum and copper and a weak connector to the cable and modem

But in all of this,
is the antenna calculated for the 850MHz frequency...???

,,,and it is advisable to use two SiSo antennas instead of a single MiMo antenna...!!!

what's your distance to the base station? in my opinion, the worst option would be an irradiator and a working mirror.
