A radar reflector is generally installed as an additional device in locations that may also be marked with a light signal; being one of its main functions the detection of targets at a great distance, thus reducing the risk of collision of a vessel.

MSM has several models of radar reflector, indicated for use on buoys or fixed structures, and designed to ensure that their signal is displayed strongly on the vessel radar screens. These models project areas ranging from 8m² to 36m².

They are manufactured by using eight overlapping spiral trihedrons, producing a strong and persistent echo, thus covering 360º. Trihedral radar reflector is best suited for applications in floating aids and in situations where there is considerable difference between the height of the radar reflector and the one from vessels passing through the area.

solid-state flashers

MSM has a wide range of solid-state flashers available, designed for marine aids-to-navigation applications. They stand out for their simplicity, flexibility and electrical protection.

These flashes include electronic circuits of the latest technology, allowing 256 preprogrammed rhythms, as well as an infinite rhythm selection.

The sunlight detector switches off the flasher during day time, in order to save energy from the battery.

In the case of MF06 and MF12 flashers, LED current output is stabilized to protect their life in service.

In the MF14 flasher, PWM modulation applies a stable and regulated voltage, in order to keep the lamp filament colour temperature.

Given the extensive experience of Mediterráneo Señales Marítimas in the field of prevention and protection against lightning, we offer a wide range of lightning arresters, surge protection and prevention products.

As lighthouses and navaids towers are very prone to be hit by lightning, in MSM we have incorporated in our catalogue safe and effective high-quality products that meet national and international regulations in force, thus achieving greater assurance and the best solution for our customers.

We offer elements to intercept a direct lightning strike on the structure, conduct current safely and disperse the discharge through the land or the sea.

The collection system is intended to intercept the lightning strike to lead to ground. Among the various standardized collection systems we offer Early Streamer Emission (ESE) or Franklin Rod Systems.

Early streamer emission (ESE) lightning rods base their operation on the electrical characteristics of the lightning formation. The ray begins with a downward tracer propagating in any direction. Once approaching to objects located on the ground, either one can be struck. They are mainly characterized by issuing a continuous upward tracer earlier than any other object within its protection radius. The rod should be the controlled impact point of discharge, so as to provide the lightning current a path to ground without damaging the structure.

Collection systems by Franklin rods consist of sharing and dissipating the lightning discharge current by a network of conductors. Sections and materials comply with the provisions of the rules defining such systems.


Complementing lightning protection systems, MSM offers a wide range of equipment to safeguard facilities and their electric equipment of surges that may occur. This product line is characterized by its robustness, compactness, ease of installation and high performance.

The range of products for the protection of marine equipment includes protective equipment for power lines, data networks and communications, photovoltaic systems and coaxial lines.

In addition to the wide range of protection products we offer, MSM offers technical support service to help you select the most suitable protection for each case.
