The Sirio M-3 is a universal bracket for mounting antennas on a mast, intended for fixed or base installations where a strong fixing point is required for compatible antennas.

Made from galvanized steel, this bracket offers good mechanical strength and corrosion protection for outdoor use when correctly installed. Its compact and robust format allows installation on masts with diameters from 35 to 42mm.

With approximate 200 x 70 x 70mm dimensions and around 420g weight, the M-3 is a practical solution for antenna systems used in base stations, communications, amateur radio, CB, VHF/UHF or other compatible applications, depending on the antenna being installed.

The bracket has 2 x Ø16mm mounting holes, allowing compatible bases, accessories or elements to be fitted. Before installation, compatibility between the bracket, antenna, mast and fixing accessories should always be checked.

It is a useful part for installation, maintenance or adaptation of antenna systems in outdoor setups, offering a simple and robust mast-mounting solution.
