Upgrading from 2.4 Ubiquiti to 5.8 Mikrotik

Hello,

I am planning to upgrade from 2.4 to 5.8GHz, but I am tight on budget so will upgrade gradually.

So please suggest me-

  1. Devices which I can use at Base station (i.e., Sectors)
  2. CPEs for home users (Someone told me Litebeam is better than SXT lite 5)
  3. I am thinking of creating PtMPs and then with the help of Omnitiks covering more areas. Is it really a good option?

Please give me some suggestions.
