Antena LTE dla Huawei B529 w T-MOBILE: ATK-20, dobór operatora, zasięg w Dębowiec, Karsin, BTS

So, yes: I live in a small town called Dębowiec near Karsin. I am surrounded by forests on each side and towards the Oder river where BTS is located there is a hill that completely cuts me off on a straight road. I can do roof measurements if necessary. For now, I was thinking about buying the ATK-20. I have three questions:
1. Is ATK-20 a good choice?
2. Is it better to choose Play and live with a funnel?
3. Which connector should I order because I can't find any information on the internet?
To BTS in Odry I have about 8km to Karsin with about 4km, because I live 1.5km from Ulica where Dębowiec begins.
Thank you in advance for your help!

It is worth doing T-Mobile tests at your place. BTS-y LTE800 T-mobile in Odry and Multi. Play range will be better because BTS in Karsin works. In Play, you can have a minimum of 100GB without a contract for a maximum of 5/15 PLN / month without a contract, then a 2Mb / s funnel is possible. How little are two cards. For LTE800 ATK-20, two pieces or ATK-10 / 800-980, also two. FME connectors and FMR-TS9 connector for B529.
