The Gibertini OP 125 L is a high-performance 125 cm offset satellite dish designed for demanding reception conditions. Its large reflector surface, stable construction and 70% efficiency provide a strong reception margin, making the antenna suitable for satellites with weaker signals at the installation location.
The reflector is manufactured from durable 1.5 mm aluminium, providing a good combination of stability, low weight and corrosion resistance. The mounting components are manufactured from galvanised and painted steel for effective protection against weather and corrosion. Its light-grey finish gives the installation a discreet appearance.
The aluminium feed arm features integrated cable routing for a cleaner installation. The antenna is supplied with a practical Quick-Fix mast clamp designed for poles measuring 55–100 mm in diameter.
The Gibertini OP 125 L operates across the 10.00–13.00 GHz frequency range and provides a specified gain of more than 43.40 dB at 11.70 GHz. Its mechanical feed holder accepts LNBs with a standard 40 mm neck diameter.

🔧 Installation
Install the satellite dish on a stable antenna mast or a suitably rated wall bracket. The Quick-Fix mast clamp is designed for poles measuring 55–100 mm in diameter.
Fit the feed arm and install a compatible LNB with a 40 mm neck diameter in the feed holder. The coaxial cable can be routed through the feed arm’s integrated cable management for a cleaner and better-protected installation.
Carefully align the dish with the required satellite. A suitable satellite signal meter is recommended for optimising signal strength and signal quality.
Because of the dish’s size and specified wind load, the mast, wall bracket, fixings and supporting building structure must be properly rated for the installation.
Professional installation is recommended when uncertain.
