SEXTANT

The SEXTANT is a 18dBi 5GHz antenna with a built in RB711 router. It has two polarizations to give you all benefits of 2x2 MIMO in 802.11n. The new SEXTANT is very similar to the popular SXT unit, just slightly bigger. Inside is the brand new RB711-5HnD dual chain wireless device, with high performance, high output power, and low power requirements. Easy to use and quick to deploy, SEXTANT is ideal for point to point links.

    Notes:
  1. All throughput tests done with Xena Networks specialized test system and RouterOS v5, according RFC2544, with Ethernet frame sizes 64, 512, 1518 bytes.
    Each board is tested with specified number of Ethernet interfaces, to ensure optimal load on hardware.
  2. Values in Italics indicate that the maximum possible throughput was reached, limited only by ethernet ports themselves.
