PETRA-9 MIMO 4x4 Unibox-2

Petra-9 MIMO 4x4 Unibox-2 is a 3G/4G antenna combined with a spacious sealed box (Unibox-2/Unibox-2L) in which you can place an LTE modem with support for MIMO 4x4 technology or two modems with support for MIMO 2x2 technology. The antenna is equipped with reliable connectors-SMA-male (50 ohms). Antenna adapters for connecting LTE modems are not included. The modem communicates with an indoor PC or router via a USB extension cable (USB 2.0).

If the router is installed inside the box, the antenna can be equipped with a sealed PG-7 or RJ-45 pin (instead of a USB extension cable)
