Sirio M-4 Galvanised Steel Universal Antenna Bracket

The Sirio M-4 is a compact and robust metal bracket designed for antenna mounting in fixed and professional installations.

Its configuration allows compatible antennas to be installed at +45° or –45° polarisation, an arrangement commonly used in mobile communication, LTE and MIMO systems.

It is particularly suitable for the Sirio SLP 4G-LTE, SY-906 and SY-910 directional antennas, allowing each antenna element to be positioned according to the required polarisation.

Manufactured from 2.5 mm galvanised steel, the bracket provides mechanical strength and corrosion protection, making it suitable for correctly assembled outdoor installations.

Important note

Before installation, verify that the mounting holes, dimensions and fastening components are compatible with the antenna and supporting structure.

The screws, clamps or other required accessories may vary according to the antenna and installation location. Use suitable hardware for the antenna weight and expected outdoor conditions.

For a two-antenna MIMO installation, position one antenna at +45° and the other at –45°, following the instructions supplied with the antenna and communication equipment.
