Huawei B715 - settings for Play, replacement, antenna selection

Hello
I have a few questions about choosing a router and optimal parameters.
I am currently using Huawei B715 (cat. 9 - as I understand it aggregates up to 3 bands) on the Play network.
HManager at the auto setting shows me that:
- I use BTS in Borowa Góra (1.4 km in a straight line) - info on BTS below
- sporadically switches to band aggregations (LTE +)

I forced the individual bands with the following speedtest results:

Band	ping	DL	UL
CAR	thirty	58,60	6.26
800	29	1.64	7.04
1800	29	17.55	4.22
2100	thirty	22.72	3.97
2600	thirty	20.22	2.24
1800 + 2100	33	28.52	5.44
1800 + 2600	thirty	45.09	4.04
1800 + 2100 + 2600	27	56,97	5.33

In the AUTO mode, the result is similar to the aggregation of 3 bands: 1800 + 2100 + 2600, however, HManager does not signal aggregation - with the + sign at LTE (LTE +) (occasionally switches to this state).

HManager results - below:
















In this regard, the questions:
1. Is the optimal solution searching for a router that supports these 3 bands (1800/2100/2600 with the possibility of aggregation)?
2. This option gives me Huawei B715, which is testing - but nevertheless it is offered mainly by Play and I prefer to buy the device independently - it is not in stores - is there any replacement at a reasonable price?
3. Is it worth thinking about the antenna in this case - and if so, which one?

LTE + will be when there is data transmission, e.g. when performing a speed test.
I suggest buying two antennas, e.g. Telkob ATK504 and using the shortest possible cable.

Thank you, I did not know about it - or maybe some suggestion about the replacement for Huawei B715 - one that at a reasonable price can be obtained on the market regardless of the operator?

I also have this router and the + symbol in Plus is only during data transmission in addition, not always, in Orange + I see all the time. The ATK504 antenna is a good choice. After connecting it and setting it "on the eye" I managed to go down from -106dB to -99dB, and after precise positioning I got -94dB, but shifting the antenna by up to 1 cm in one direction immediately causes a decrease of 1-2dB. I will only add that the set is mounted under a roof so the cable does not have anything except the piece that comes out of the antenna. Why do you say that this router from Play does not aggregate 3 bands? You have the best transfer with 3 bands.
