Βάση κεραίας Extralink L250x400

The Extralink L250x400 antenna holder is a galvanized steel wall mount designed to securely support satellite and terrestrial antennas on building facades and other flat surfaces. With overall dimensions of 250 x 400 mm and a silver anti-corrosion finish, this bracket combines straightforward construction with weather-resistant materials to provide stable, long-term outdoor performance. The bracket accepts an arm length of 250 mm and a vertical plate height of 400 mm, with tube diameter 38 × 1.5 mm for attaching the antenna mast.

Advantages

The galvanized steel construction ensures resistance to rust and typical outdoor wear, extending the service life of the mount. Its simple, compact design makes installation quick and requires only standard tools and fixings. The 250 mm arm provides sufficient clearance from the wall to reduce signal obstruction, while the 400 mm vertical plate offers multiple fixing points for secure anchoring to masonry or other solid surfaces. The silver finish is durable and low-maintenance.

How to use

Position the bracket on the chosen flat surface and mark fixing points through the vertical plate. Drill appropriate holes in the wall material and secure the plate using suitable anchors or bolts for the substrate (masonry, concrete, or structural wall). Attach the antenna mast to the 38 × 1.5 mm tube section and tighten clamps or fasteners so the antenna sits at the required azimuth and elevation. Check that all fixings are tightened and the bracket is stable before completing cable routing.

Recommendations

For best results, use corrosion-resistant fasteners appropriate for the wall material, verify load limits of the supporting surface, and periodically inspect mounting points after severe weather to ensure continued stability and signal alignment.
