Splitter question

I don't think mediacom has anything above 1 ghz running on their system for any customers. Those signal levels are great but don't let your upstream get any higher. Would rather see it in the mid 40's

That's what I thought about the splitter. I was thinking my upstream was in mid 40's before Mediacom tech was out and changed everything from the pole to modem out. I can't remember when it went to 50. I wonder if my splitter did it? I know the tech put a newer filter and I have no splitters other than at the modem anymore. At least there are none in the box now.

Mediacom tech gave me a new splitter and it didn't change anything. Since everything is new from pole to my modem I'll assume this is as good as it gets or at least whatever is putting it at 50 isn't in my home.

are you -1 to 0db with the splitter in place, or is that without it

is the 50db upstream with or without the splitter in place

if you follow the line in from the pole to the house are there any splits or splitters with only one port used anywhere in the mix?

There has to be something in the mix knocking off signal, because with those signal levels as is, it would be impossible to get a customer with HSD and video into spec.

I have seen problems with cheap (insert unpronounceable Chinese company name here) splitters before. You can usually spot them by looking at the back (or bottom) of the splitter. If there is a bead of hot glue going around the outside edge of the back cover, you have one of the cheap splitters.

If you find a bead of metallic looking solder running around the edge, then it is better made. Because of the solder, the back cover can shield out stray RF better.

Most dish splitters look like two molded halves sandwiched together. They have one path that is designed to pass DC to the LMB at the dish. These are good, but overkill. (if you already have one, use it).

Whenever possible, always use a 2-way splitter going to the modem first before any TV's. They are usually -3.5dB, and any cable modem should be able to punch through them fine.

As a rule of thumb, always make sure the cables are in good shape and properly fastened to any splitter too. I have seen more cable related problems than splitter problems in the past.

Hope this helps,
