Customer ownership is all about creating and deliveringcompelling value. If youre building out anexisting SCADA system, or just getting started on one, a sure-fire way tocreate this value lies directly in your hands: by building in long lasting systemperformance and impeccable reliability.If we set aside the radiopreference for the moment, the single most important key to more reliable SCADAcommunication results from careful selection of antenna equipment.Increasing Reliability Tenfold Ruggedized parts, optimized assemblytechniques, and specialized coatings, along with improved installationprocedures can, in some cases, deliver a tenfold (10X) increase over thelifespan of traditional aluminum antennas.Cost effective The Yagi-Uda, more familiarlyknown as the yagi, stands out as the pre-eminent antenna-of-choice for most remotesite applications. Some SCADA systems mayutilize up to 1000 Yagis pointing to an omnidirectional antenna; a highlycost-effective configuration that ensures broad geographic range at minimalcost! Given the continuous exposure tothe elements, though, susceptibility to damage from wind, weathering and in somecases, chemical exposure, remains high. We consider mean time between failures (MTBF)a critical economic consideration when the cost to travel to the field toreplace a broken or defective antenna can easily exceed $100 an hour. It makes real sense, then, that increasingMTBF through investment in better antenna technology can very quickly pay foritself.In some cases, a 25% pricepremium for antenna equipment may extend your sites operating life from 12- 24months to up to 10 years, depending on the installation in question!Selection Criteria =>The antenna design, aswell as the actual manufacturing process exerts the greatest influence on thelong term performance and life-span of an antenna. Consequently, seek out demonstrablysuperior designs that incorporate sturdy materials and exhibit well-built construction.=>Antennas manufacturedwith 6061 aluminum offer the best combination of strength and light weight. =>Welded models typicallyprovide the greatest long term performance as they remain one piece, both electricallyand mechanically, under virtually all environmental conditions. In particular, avoid press-fit antennadesigns. =>Pitting and corrosion occursrather quickly with untreated aluminum, leading to rapid mechanical deteriorationand electrical non-performance within as little as 2 years. Therefore, choose onewith either thermoset (powder coat) oranodizedsurface treatment; avoidthose treated solely with chemical conversion coatings (Alodine). What else to consider =>In addition to antennas,pay careful attention when choosing a feeder cable. In a typical SCADA system,the cable connecting the antenna to the radio enclosure endures the same environmentalconditions as the antenna. We recommend that cable for the antenna feed should matchthe life expectancy of the antenna. =>In order to maximizethe overall life of the installation, use a UV resistant, low loss RG-8 typecoax cable, preferably with a poly-ethylene (PE III-A) jacket, and terminatedwith N-type connectors. Using the wrong cable can cause huge reductions inefficiency. You cannot recover these losses with any amount of antenna gain ortransmitter power.=>Follow the manufacturersinstallation guidelines, usually included with each antenna.=>Ensure antennastability; lightweight,unstableantenna mastsorloose,poor quality clampscan create problems.=>Insist onapplication-specific weatherproofing, whether your own staff is doing the work,or its being done by a contractor=>Pay attention to properinstallation procedures; this contributes hugely to the overall life of theinstallation.
