Re:Return path Problem w/ Modems

It sounds like the trouble is with the forward. You are lowering the input level to the modem below its spec. Min 3.0 dBmV. Drop me a line to (-REDACTED-) I do alot of testing on cable modems and the main problem is the lack of signal.

>I install a lot of cable modems. Have installed several kinds but the ones I'm havinf trouble with is the GI Surfboards. The cable modem is external and connects to an ethernet card.etc,etc,etc,
>the problem is that when it is hooked to a four way splitter or eight way the modem becomes unstable or works intermittingly. I use primarily Regal Gold 120db EMI or Tru Spec 120dB EMI. The modem would work fine thru a 2way or three way but 4's and 8's would kill it. The RF being sent back was 19MHz and it measured 45db before the 4 ways and 45 dB out of the four way input. This was very strange and have no explanation for it.Has anyone come across this before or know why this happens. It is easily gone around to get it going again but the WHY is peckin at me. help if ya can. Thanks
