We wanted to knowwhy ELDTEC doesn’t export any of theirproducts and decided to visit them inthe city of Aruja, about 40km from SaoPaulo.So we hopped on bus route 166 thatgoes from the Metro Station Arménia(Linie 1) and travels directly to Aruja.ELDTEC’s 5000 Sq-m fabrication facil-ity can be found in the industrial park.Our company contact is Eliseu Diasfrom Technical Support. He is himself asatellite enthusiast and has six disheserected at his home. He explains, “140employees work here and produce6,000km (about 3,700 miles) of coaxialcable every month.” In addition to meshdishes for the C-band, UHF antennasare also produced that are not only soldunder their own name but are also soldfor private labels as OEM products.“ELDTEC was founded in 1992 bySenhor Laerth with just a few employ-ees”, explains Eliseu Dias about thecompany’s history. The first productswere mesh dishes; in 2002 smaller steeldishes for the Ku-band were added andCOMPANY REPORT Dish, Antenna and Cable Manufacturer ELDTEC, Brazil

Thedishes are tested on a long-termbasis.in 2003 the company began producingcoaxial cable. “In 2004 the companymoved to its current location in Aruja.”How are things looking in sales? Thiswas a question for Sales Manager Jef-ferson Cruz who runs a team of sevenregional sales managers. We wantedto know why ELDTEC does not exportany of their products: “We can’t matchthe prices of our competitors”, he ad-mits openly, “We often pay more for thematerials than our competitors chargefor the complete product.” Even thoughtheir production operation is exception-ally organized, the company can’t reachthe price levels of the world market.“We would love to export”, says Jef-ferson Cruz, “but aside from the pricesthere are still other hurdles relating toproduct shipments across the border.”But who knows, maybe ELDTEC willfind a way to compete with the priceson the world market and jump overthose exporting hurdles. Then ELDTECwill also become known outside of Bra-zil.

A palette of terrestrial antennas ready to be picked up.4. Eight machines punch out the mesh panels. The rollsconsist of 0.55mm thick sheet metal that is fed into the punchmachines.5. The mesh material comes out at the other end which will thenbe cut into the proper panel sizes.

A drum containing nearly 700kg (1,500 Lbs) of copper wire in theprotective cage.2. The copper wire is fed at a speed of roughly 13 meters/second (43 feet/second). The first stop is this machine which stretches the wire so thatany possible production failures can be eliminated.3. The cable production control box. The speed is shown in the upper leftat 12 m/s (about 40 feet/sec).4-5. The first step takes place here: making the internal dielectric spacer.The plastic granules are heated and coated around the wire passingthrough the machine. This process heats the wire to about 220°C (430°F).The wire first has to be cooled before anything else can be done.

The wire is passed through a 46m (150-foot) long water-filled pipewith 13 cooling stations such that by the end the cable is cooled to 50°C(120°F).7. A look inside one of the cooling stations. Just like the pipe, it is alsofilled with water. The wire runs through here and gets cooled in theprocess.8.Technician Anderson Lopez is in charge of Cable Production. He says,“Here at the end the wire has reached room temperature so that now it canbe wound up. 5km (about 3 miles) of wire can fit on one roll.”9. The coax cable is now only half finished. The shielding is missing. Thismachine takes care of that: 16 rotating spindles (8 above and 8 below)create the outside braid. Technician Anderson Lopez explains, “It involvesaluminum wire with a diameter of 0.6mm.”10. This is how the raw coaxial cable comes out of the machine.11. Now the last step: The outer protective sheath is added to the rawcoaxial cable. This process is similar to the application of the innerdielectric: The raw coaxial cable passes through this machine at a rate of50 to 120 meters/minute, or 164 to 390 feet/minute (depending on cabletype), is heated to 200°C (about 390°F) and is then coated in a plasticprotective jacket.12. The completed cable is once again run through a water bath to cool itoff but this time it’s only 20m (65 feet) long.

The last step: thecompleted coaxial cable isrolled into 50 or 100m (165 or330 foot) bundles using thismachine.14. Wait! There’s somethingmissing! The cable stillhas to be labeled. Thistakes place right after theapplication of the protectivejacket while it’s still hot. Thisstamp imprints the cabletype onto the protectivecover.15. This is the keyboard usedto enter the cable type.16. He is responsible forall of ELDTEC’s productionoperations: ProductionManager Jose Dos Santos.
