Internet PLUS LTE: Best Antenna for 5.35km BTS Distance, MIMO 15dBi, Cable Length & Tree Obstacles

Hello,
I am going to test the lte internet plus plus, according to the maps of lte coverage of various operators, plus has the best coverage in my region. BTSearch does not search for LTE plus stations so I assume that those with GSM1800 will also have LTE1800.
The nearest bts is 5.35 km, then there are several bts at distances of at least 8 km.

Is there any chance of getting connected at such distances?
Is it enough, for example, such an antenna: http://www.cybertech.com.pl/p115,antena-dualna-lte-4g-15dbi-mimo.html?
Does the length of the antenna cable have a big influence on the signal strength? I want to mount the antenna as high as possible because there are quite a lot of trees near the house.

And what is the significance of the operator coverage maps? None, they are often outdated and virtual. The operator is selected on the basis of tests of each in a specific location, for pre-paid cards and LTE phone tests with the Network cell info application. Shows signal parameters and BTS data, plus speed tests. Plus voice cards after registration 50GB bonus, Orange voice cards for 5 PLN, registration in the salon where you enter the address for which you have a 100GB bonus. Free T-Mobile with 20GB and Internet Play for PLN 9. Based on the tests, you choose a subscription offer with hardware or a pre-paid offer from Play (unlimited LTE internet for PLN 5 / month) or Orange (pre-paid Orange Free, a card for PLN 100 on Allegro with a limit of 1410 GB for 18 months). Plus does not have its own LTe network, it uses LTE1800 Aero2 or LTE800Sferia (many permits have not been implemented, the operator has only been expanding the network for half a year). The antenna is selected for a specific band. What's the location?

When it comes to t-mobile and play, catching 3g is a problem near my house, so I do not see any other option how to mount the antenna as high as possible and then try to catch the signal from some bts. Alternatively, near the given bts, I will check the signal parameters. I'm not very much on the topic, is this btsearch data up to date? Maybe see for yourself, two screens show my location and the distances to the two bts I wrote about:

The nearest LTE permits for Plus are located in Wola Kamborska. these are LTE1800aero2 and LTE800Sferii. it is difficult to verify if they work and how. The coverage map of Plus and CP does not work. You need to do a signal and speed test on the Plus card using the LTE phone and the Network Cell info application, which will show the signal parameters and BTS ECi eNB by which you can identify it. The same permit in Haczów. 3G on Plus with UMTS900 aero2 from these locations. Distances of several kilometers, so an antenna for the selected band is necessary, which will turn out after the tests. In addition, LTE coverage in Orange and T-mobile with BTS LTE800 NetWorks on the Orange license in Wola Kamborska and 3G with UMTS900 from it. Additionally LTE1800 NetWorks from Korczyna but weak signal. Play coverage on LTE800 from BTs Play in Krosno, korczyńska 57 or Sikorskiego 19 and the weak LTE1800 from it. The key question when it comes to Plus is whether the permits in Haczów and will K. work and on what LTE band. The other operators have BTS confirmed.

Ok, tomorrow I will try to check T-Mobile and plus. Once I have an ECi, how can I check which bts is it? You can also somehow check in what band the signal is received?

BTS NetWorks LTE1800 and LTE800 t-mobile are usually verified and after ECI, eNB you can check which and which band. Worse with Plus, but here, after ECI, you can recognize eNB and locate BTs, worse with LTE band.

Ok, I was able to test LTE in two locations on two smartphones, t-mobile and plus networks.
I tested in these places:

So first in my town, and then in Kombornia, some 200m from the bts.
The first smartphone is the LG G2, it probably only supports LTE800 because it did not catch on another band. I was able to root it so I was able to check the frequency.
The second is Chinese with the MT6735 chip, it is to support the 800/900/1800/2100/2600 bands. He didn't have root so I couldn't check.

I collected all 5 tests in the picture below:


As you can see in the first LTE location, I only caught the LG G2 and only on the plus card. It turns out that it's bts in Haczów (3 lines from such a distant bts ?!). In the remaining four cases, I joined bts in Kombornia. The band on which I had LTE in Chinese remains a mystery, because the download was quite large compared to other tests.

After returning home, I found options in the service menu to select individual bands, if it really works, tomorrow I will check the plus on quinol again.

Added after 10 [hours] 7 [minutes]:

It worked, the transmitter in Kombornia has two plus bands, LTE1800 and LTE800. The former has a much better speed (50Mb / s):


So the 1800 antenna would be the best. The same antenna is enough for LTE Advanced?
