In order to keep up with the huge growth in wireless communications, and in particular, with the explosion in GSM-based applications, Otto Marketing, a long standing manufacturer of quality cable assemblies, has now established a dedicated RF cable assembly facility.
This was facilitated by its recent move into its new 1000 m² industrial premises in Strijdom Park, Randburg.
In order to ensure the highest standards of quality and workmanship, the company says that various tools and equipment were evaluated, and then the most accurate and effective items were purchased. These include two precision coaxial-cable stripping machines (a Komax BT-86 and a Schleuniger Coaz-Strip), an Anritsu Sitemaster S331A RF cable loss and insertion loss tester, an Oristec precision cable measurement and cutting machine, two Komax compressed-air crimping machines, a CMK900 electric crimping press, as well as a wide variety of crimp dies for these machines.
Selected assembly staff received IPC training in RF cable assembly and testing, and Otto can now supply a wide range of RF cable, connectors and cable assemblies, including: N type, BNC; SMA, SMB; MCX, MMCX; H.FL, U.FL; RG174, RG178, RG316, RG400.
All cables are tested for both mechanical conformance and electrical performance. They are tested for insertion and return loss on the Ansitsu S331 RF tester, and if required, performance graphs can be supplied with the RF cable assemblies.
Otto has already supplied many thousands of RF pigtails and cables to customers to connect GSM modules to external antennas. It was a logical step then, it says, to sign a distribution agreement with a leading antenna manufacturer, Joymax. Otto is now able to supply a large selection of RF antennas for numerous applications.
The most popular applications are currently GSM, GPS, LAN and VHF. The GPS521 active external GPS antenna is one of the most popular items at present. Antennas are available in many different styles (stubby, magnetic, window or wall mount, etc).
