ratchet Posted July 25, 2005 CID Share Posted July 25, 2005 Upstream is down to 38 which is good, however, since downstream should be between -15 and +15 what are the ramifications of it running this high? Thank You! Quote Link to comment Share on other sites More sharing options...

Thank You! You are approaching the upper threshold, but it most likely won't be an issue until the weather cools down. By winter you may be up in the 20's, and that will defiantly be an issue. Where did you install the amp? If you can, you may want to by-pass the cable modem line around the amplifier by installing a 2 way splitter at the input of the amp. One leg feeding the amp, the other feeding your modem. I have attached an ultra high quality diagram (made with MS Paint) to help explain....

ratchet Posted July 25, 2005 Author CID Share Posted July 25, 2005 Thank you for the reply! The reason I installed the amplifier is because during the evening, the upstream level was often 58dBmV. Actually, I thought I might install the splitter after the amp and hope the upstream level winds up somewhere between 38 and 58. Quote Link to comment Share on other sites More sharing options...
dn0 Posted July 25, 2005 CID Share Posted July 25, 2005 Good idea. What are the specs on the amp? Does it say it amplifies the 5-42MHz spectrum? Most amps do not, but it sounds like your's does. You could stick another splitter in line to help attenuate the RF a bit. That would lower the RX, and raise the TX which would not hurt either, you have plenty of head-room.

ratchet Posted July 25, 2005 Author CID Share Posted July 25, 2005 It worked! New readings 12 and 43. This is a good compromise for now. Thanks again dn0! Quote Link to comment Share on other sites More sharing options...
