WWOR Fox Ch9

  1. 1. Empire State Building-N.Y.-FOX CH9 Catalin Popescu - 2002
  2. 2. Project Goals <ul><li>60Kw-VHF transmitter – CH9, parallel configuration system; </li></ul><ul><li>RF system to allows any combination between the pair of the 30KW TX’s and antenna systems available </li></ul><ul><li>System switching done automatically/manually, no interruptions; </li></ul><ul><li>Line optimized (VSWR better than 1.07), good insulation between the combined paths (more than 60dB) </li></ul><ul><li>Remote Control operation, with Local mimic panel for the RF system patching. </li></ul><ul><li>Design the system for installation into a room with ceiling restrictions, minimum distance to the walls, 18”, air ducting, and complete in two phases. </li></ul>
  3. 3. Description <ul><li>RF system design according with the customer specifications. </li></ul><ul><li>Submission and approval of the proposal. </li></ul><ul><li>Manufacturing and Installation drawings. </li></ul><ul><li>Remote Control design for the application. </li></ul><ul><li>Helping the Test and Service Dept. in the final commissioning </li></ul>FOR MORE INFO... Mr. Catalin Popescu – Application Specialist Phone: 905 564-9222 Fax: 905 564-9224
  4. 4. RF system design <ul><li>System parallel configuration is designed to use: </li></ul><ul><ul><ul><li>two VHF 30KW transmitters, </li></ul></ul></ul><ul><ul><ul><li>two Diplexers, </li></ul></ul></ul><ul><ul><ul><li>A Contactless switch, </li></ul></ul></ul><ul><ul><ul><li>and Patching system; </li></ul></ul></ul><ul><li>The transmission line used is : </li></ul><ul><ul><ul><li>1-5/8” for aural; </li></ul></ul></ul><ul><ul><ul><li>3-1/8” for visual and combined (aural +visual); </li></ul></ul></ul><ul><ul><ul><li>4-1/16” for combined transmitters; </li></ul></ul></ul><ul><ul><ul><li>6-1/8” for the Antenna Lines. </li></ul></ul></ul><ul><li>The key factors for design where: max line avg. power, VSWR derating, insertion loss contribution to final power at the gas barrier and space limitations. </li></ul>
  5. 5. RF System design (cont.)
  6. 6. . Submission of the proposal <ul><li>The RF diagram showing the modes of operation for the system; </li></ul><ul><li>The material list count: lines, elbows, couplings, reducers, coaxial switches, probe sections; </li></ul><ul><li>Electrical Diagram design for the 208/120VAC service (breaker size, surge protection, voltage regulation) </li></ul><ul><li>Exciters ( 3 exciters) patching panel designed by Application Dept. </li></ul><ul><li>Mimic Panel and RF switching custom Controller design by Engineering Dept. </li></ul>
