Hi All,

Currently have 3 TV's and Comcast cable modem. The splitter in the
cross space has a total of 5 ports.

1. Comcast in
2. Cable modem
3. TV
4. TV
5. TV/DVR

I would like to add an additional TV.

Can I just purchase a 6 port cable splitter ?

Will it reduce the quality of the signal ?

Any input would be appreciated.

You need to get a two way splitter (3 ports and preferably a quality one
from the cable company) and a short coax cable. Connect the incoming
cable to the input of this two way splitter (yes the port labeled input
makes a difference). Move the feed to the cable modem to one output of
the two way splitter. Connect the input to the four way splitter to the
other output of the two way splitter. Connect new TV to the port on the
four way splitter freed by the cable modem connection.
