Just the telecom company demolished my everyday used tower thus the spare tower is giving.... oh! 8 bits per second with latency 180 000 miliseconds and 97.9% of data packets corrupted. Level -113 dBm, thus seems obvious that I ought to use a good MIMO LTE antenna with a least some 20 dB amplification and all will be back good again. Yet when telecom demands to buy a 2 dB antenna for 170 Eur it seems not so normal, thus I found in shelf one 600-2700 MHz logo-yagi, but it is one not a two. As my SISO/LTE modem have dedicated for 2x2 MIMO, I am bit in disorientation how to apply one single. Clear, one cable v.s. two cables means 2x less speed. If genuine speed is 300 MBps I bet its enough for me with 150 MBps let internet just roar. But then what to do with unused input?? Just to let open so the inner mini-antenna is operated??? May someone give me dummies primer what is circuitry (I mean inner cabling) around those 2x2 MIMO thing in data servers!
