Can you make a point-to-multipoint scheme?

Yes, RB711-5HnD comes with L4 (AP) license.

I have RB711-5HnD - not new, is the license free?

Well, it’s not free actually but bound to the (disk on the) device and being paid for with the purchase of the device. As long as you see a running routerOS when it’s booted, you’re safe.There’s no recurring cost.

If I log into routerOS is everything ok?

Login and navigate to System → License to check the actual licence level.

Thanks everyone for the advice.
How to tune antennas in point-to-multipoint mode?

Software ID : #####
Level : 3
Features : null

It means this device can only work as a wireless client.
You would need Level4 to accept clients and work as Access Point (multi point mode)

Check the license levels table to see the difference between level 3 and level 4 (which nowadays most RB devices come with). The only big difference is that it’s not possible configure a level 3 device as AP, it can only be client. In your PtMP scenario it can be one of “rim” elements but it can’t be a “hub” (speaking in bicycle wheel nomenclature).
