Recently I had the Disk Network Hopper and 3 Joeys installed at my house. The joey in my computer room shares a cable with my Comcast cable internet service. I never had a problem running my satellite tv and cable internet through the same coaxial cable until now. Prior to switching to Disk Network, I had Directv and it worked fine sharing a coaxial cable with my Comcast cable internet. I had a 5/2150 2-way splitter combining the signals at the junction box on the outside of my home and another 5/2150 2-way splitter separating it at the outlet in my computer room.

The Disk Network technician tried this same hook up using 2 Holland 5/2150 HFS-2D splitters and it does not work. The satellite signal comes through fine, but the cable internet will not work. When I connect it with using the old splitters that worked when I had Directv, which is an Aska 5-2150 Diplexer on the combining end and a Holland DPD2 5-2150 on the splitter end, the Comcast internet signal comes through fine, but the satellite does not work.

I would really like to run the satellite and cable internet through the same coaxial cable. Do I need a special signal combiner/splitter?

Any help is greatly appreciated.

#1 - get separate cables for the Comcast Internet and your Dish. Sharing cables is a surefire entry into fingerpointing between providers.

#2 - You have to use Diplexers in PAIRS. However - I don't know what frequencies the Joey is using, so again - go back to separate cables. They may very well be using the same band. If you didn't have the Hopper / Joey setup - then your old DirecTV setup using the diplexers would have worked.

#3 - There maybe some other network technology (ethernet, wifi ?) to connect your Joey to the Hopper, and leave the coax cable for the cable modem..
You CAN put antennas on your owned and/or controlled property...

Most Hopper/Joey setups are not designed for coax to work with other providers due to the number of frequencies they need to use. A separate run for your internet is the best possible solution.

You cannot combine them at all. The Hopper requires the entirety of the cable's bandwidth.
