Televes Corporation

The engineer who commissioned the first RAS machine

Antonio Gándara, industrial master with the soul of an engineer.

In the history of Televes, there are names that will be remembered forever. One such name is Antonio Gándara, an industrial master with the soul of an engineer, whose talent and character marked one of the key moments in the company's development: the commissioning of the RAS machine in 1965.

His history at Televes began with Ricardo Bescansa, president and founder, with whom he shared a practical and ambitious view of technology. A collaboration was born where Ricardo's ideas flowed and took shape in Antonio's expert hands. This relationship of trust became a professional friendship and, above all, one of the pillars of Televes' first great technological challenge.

Those who worked with him remember Antonio for his direct, demanding manner, but also something much more important: he was brilliant. He did not need big speeches or unsupported theories. He was able to demonstrate with deeds, with lathes, with milling cutters, with millimetric adjustments that turned an idea into a reality. He was a workshop man, but with an engineer's mind.

Televes' first major strategic move was the decision to manufacture our own aluminum antennas. This was a visionary decision that went against majority opinion, given the supply issues with this material in the 1960s. There would be an added challenge: the purchase of the RAS machine, a piece of German equipment designed to manufacture aluminum tube from strip, and induction weld it with radio frequency. This was a risky exposure for the young company, which invested 1,950,715 pesetas in acquiring the machinery in 1965—almost half of its annual turnover—for a technology that simply did not work.

When the delays stacked up and the facility was still not operating, Ricardo Bescansa decided to travel to Germany. And he did not hesitate to ask Antonio and Mr. Herbert, a German living in Spain and hired by Bescansa, to accompany him.

When they arrived in the city of Sindelfingen, near the Mercedes Benz headquarters, they found that the machine, designed by RAS for tube forming and AEG Elotherm for induction brazing, was assembled in a wooden storehouse outside the factory because it was too large, and surrounded by engineers who had no idea why it wasn’t working. They were stuck, overwhelmed by the challenge. The 12 mm tube didn't work, the 26 mm tube failed, and the German engineers didn't know how to solve it.

With the calculations made by Mr. Bescansa and with the support of Mr. Reihart, engineer and founder of RAS, Antonio Gándara and the rest of the technicians analyzed, disassembled, adjusted and modified the machine. He made changes to the production lines and induction coil. He did so by interpreting detailed information in German and the electrical schematics of the induction system. They calculated the values of the coil over and over again, reducing the length of the coil, to see if it was within the tolerances marked on the schematic. The final proposal to reduce the coil was not approved by AEG, but it was approved and authorized by Mr. Reihart.

And so 12 mm aluminum tube was welded with RF, according to the Germans, for the first time in history. Engineer Reihart would later confess to Bescansa that “that young Spanish engineer was very good.”

And so Antonio Gándara was. And not just because of that day in Germany. His legacy encompasses much more: structures, shipbuilding, even aeronautics. But it was at Televes where he left an indelible mark: On that RAS machine, which is still in operation today, modernized thanks to ISF engineering, but with the same spirit as then: that of solving an impossible problem, with talent and audacity.

Remembering him today is much more than paying tribute. It is to recognize that behind every advance, every innovation, there are people who made it possible. Antonio Gándara was one of those people. And his history is part of the soul of Televes.

New Overlight Series set top boxes

An international award-winning modular design

The Overlight Series continues to evolve with the launch of the new generation of optical receivers, compatible with multiple receiving technologies and satellite operators. Thanks to its optimized electronic performance and low losses, it is possible to reduce the number of amplifier devices required and simplify deployment in collective installations, while preserving end-to-end signal quality.

These devices have a completely renewed look and feel, winning four prestigious international awards for design and modularity. Its manufacture in zamak creates an optimal balance between robustness and lightness, with excellent shielding against interference.

The basic principle of the Overlight Series remains intact, with two main elements in the installation: the optical transmitter, which receives the RF signals from the antennas and converts them into an optical signal for fiber transmission, and the optical receivers, which receive this signal and convert it back into RF for reception at the end devices.

Thanks to the high output power of the transmitters and the low losses of the fiber, Overlight makes it possible to carry the TV signal over long distances and distribute it to up to 64 users completely passively or 512 by using an optical amplifier. These characteristics give it great flexibility to tackle projects of different scale and complexity. The multiple wavelengths available allow for multiplexing the optical signals from several transmitters to distribute up to 4 satellites and DTT over a single fiber, and additionally integrate GPON.

This range of set top boxes covers all three receiving technologies: Quattro, Quad and dCSS, making it possible to reach all types of installations:

The Quad model (ref. 237650) allows direct connection of up to 4 set top boxes, and is key for FTTH and FTTR.

The Quattro model (ref. 237640) is designed for direct connection to a multiswitcher, facilitating distribution in a collective installation, for FTTB or even for FTTR with several satellites.

The dCSS compatible line includes models with 2 and 4 outputs (refs. 23762x and 23763x respectively), which are specifically configured for the UBs (User Bands) typical of the countries and satellite operators that have implemented this technology.

With this new generation of optical receivers, we reaffirm our commitment to innovation in television distribution, offering an advanced, efficient, and future-proof solution.

FAQs

How do I splice two sections of optical fiber?

Various methods can be used to join two sections of optical fiber, although the most common methods are mechanical splicing and fusion splicing. A mechanical splicer is an acceptable option for occasional use. However, even though the tool is affordable, this advantage has to be weighed against the cost of the splice materials, which is 10 times higher than the cost of a fusion splice. If a poor result is achieved, the splice material cannot be reused, and specific optical equipment must also be available just to detect the problem. For all these reasons, fusion splicing is the best option for professionals who regularly work with optical fiber infrastructure. A fusion splicer measures optical losses after the fusion splice is completed. This provides secure information that the fusion has been performed correctly, and if it has not, the splice can be repeated at no extra cost. This method greatly reduces uncertainty and the possibility of flaws in the optical fiber cable.

In the case of specific applications where the lambdas are defined, such as for certifying telecommunications infrastructure under Spain’s ICT2 regulations, it is possible to find devices that automatically take all of the optical measurements. This saves time and effort for the installer because the same process does not have to be repeated for each lambda.

Finally, a professional fusion splicer presents a fast, simple, and reliable fusion process as long as the steps are performed in the appropriate order.

Importance of sheath materials for telecommunication cables

Keys to choosing the right one for each installation

The choice of sheath material for cables such as coaxial, data or even fiber optic, is a critical factor that directly affects their durability and safety, and therefore their performance over time. The sheaths protect the core of the cable, where the information travels, from external aggressions, but not all of them are designed to withstand the same conditions. Below, we analyze the most common materials according to their application:

PVC sheath:

the usual solution for conventional indoor installations

Polyvinyl chloride (PVC) is a common choice for indoor applications, although the current CPR (Construction Products Regulation) of each country must be taken into account. This material offers good mechanical resistance, although its behavior with respect to fire and the emission of toxic gases limits its use in crowded spaces. It is not suitable for outdoor installations as prolonged exposure to solar radiation or moisture can quickly deteriorate it.

LSFH sheath:

safety in public spaces and in specific outdoor applications

LSFH sheaths (Low Smoke Free Halogen, also known as LSZH or LS0H), are designed to minimize the emission of toxic and corrosive fumes in case of fire. This makes them the best choice for indoor use in high occupancy environments such as hospitals, shopping malls, airports or public buildings in general. In addition, if these sheaths have been treated with additives resistant to ultraviolet (UV) rays, they can also be used in short exterior installations, such as downspouts on facades. It should be noted that, at present, the legislation in some countries expressly requires the use of this material in specific high-occupancy scenarios, as is the case of common telecommunications infrastructures in Spain.

PE sheath:

Outdoor use and underground wiring

Polyethylene (PE) sheaths are common in outdoor installations due to their excellent resistance to moisture, UV rays and atmospheric agents. However, it is important to note that they are not intended to be buried directly in contact with the ground. Their use in underground wiring is permitted, provided that the cable is placed inside a suitable resistant conduit, which insulates it from direct contact with the ground.

When greater protection is required, the use of cables with integrated Petro-Gel can make all the difference. Petro-Gel is a water-repellent mineral compound with a high melting point that is incorporated as an internal filler, preventing moisture from entering and protecting the integrity of the cable even in very demanding environments. Although this combination allows for more reliable performance in outdoor installations, it is still not sufficient to classify the cable as suitable for direct burial in the ground, as they often lack other essential features such as rodent protection or double mechanical shielding.
