Mikrotik Sxt SA5 ac 802.11ac up to 540Mbit, 1300mW RF output, with 90deg. sector antenna

The new AC standard is here, with up to 866Mbit over the air datarate,
256-QAM modulation, and 80MHz channels. 802.11ac opens up new
possibilities and speeds never possible before.
The SXT ac is a new member in our 802.11ac product lineup, currently
two models are available — with regular 28 degree antenna, and the SA
model with a 90 wide beam- width sector antenna. Also supports
802.11a/n mode and is compatible with all legacy RouterBOARD devices,
including Nstream and Nv2 protocols. Both devices come with Gigabit
Ethernet.
New products are backwards compatible- for example, you can replace
your 5GHz 802.11an legacy Access Point with new 802.11ac product and
your existing customers will still be able to connect to it.
