Hi everyone! I am forced to change the equipment I received from my ISP (my new offer does not include equipment rental). I'm currently using an MF258 bundled with an outdoor antenna (I think it's actually an outdoor access point, since it's powered via PoE and has a SIM card in it). Currently, I am moderately satisfied with this AP, I am about 2.5km from the BTS, there are almost no obstacles in the path of the signal, and yet, the signal strength has strong fluctuations from 100% to 30%, regardless of the weather or season, I should add that the antenna is mounted very stably. I would like the new antenna to have better performance than the current one, and to be powered by PoE, currently I do not have the possibility to install additional wiring outside the house, so I would like to use the existing wiring. The home router is not important in this case, an AP with PoE power supply is enough for me. My budget is about 150-200 usd. I am not entirely familiar with the selection of devices of this type, so I would like to ask for your help.
I attach the speedtest results, BTS parameters and screenshot about the used band in the router menu.
