Hello, I have a router as in the topic and I need to buy an antenna for it to strengthen the lte signal. I have 7.4 km to the nearest one and from which I use bts. The frequency running on it is 800mhz and no other. At the moment, the router is standing on the windowsill and the strength with which I receive the signal is - 108 to - 111dB and the data from the router. On the roof, I checked with the phone with the Network Cell info application and there it ranged from - 79 to - 89 dBi. Therefore, what antenna do you recommend, I was browsing alledrogo and there is a whole lot of it. I am asking for advice.
Best regards.
