DOWDEN COMMUNICATIONS INVESTORS', L.P ENGINEERING REPORT Page 1 <br />TO: Mary Smith <br />FROM: David Eng � <br />DATE: December 15, 1987 <br />RE: Regional Channel <br />CC: Stuart V. Gibsor <br />The following is a brief overview of the possible interconnection <br />techniques that we have studied to date. <br />OPTION et <br />Discussions with Jim Sullivan on 11-23 and 12-03 have reaffirmed <br />our earlier findings with the line of sight problem with the new <br />Pillsbury tower. Jim was to send me more information on costs and <br />and technical considerations. I have not received any correspondence <br />to date. The only price we have discussed is for the microwave feed <br />feed with the amount in the $60,000 range. This feed would r.,me <br />Chaska. I will continue to explore this option. <br />OPTION e2 <br />This concept is to connect our system with the Rogers system with <br />a possible tie at the Deephaven School. We would need to place <br />translation gear at this location to take the channel off the <br />Roger's system and place it on sub -low to send to the Excelsior <br />hub. From this point we would send the signal back to the Mound <br />Headend for distribution to the subscriber network. The signal <br />traveling this route would pass through 81 amplifiers before <br />reaching the extremities of Dowdens system. Signal to Noise would <br />be 39 dB, which is noticeably inferior. The estimated cost of <br />this connection would be in the $ 30,000 range. Tony Werner, <br />Vice President of Engineering, Roger's Cablesystems, is currently <br />conducting an engineering study so that I may calculate an <br />accurate picture quality and reliability factor. <br />APPFNI,TS P <br />
