Not a good idea. Connecting an antenna to the coax upstream of the cable
modem could cause problems by reducing signal strength and adding noise,
especially in the range of the modem's upstream channel. Much better to
use a separate cable for the antenna.
Forget that whole mess. Make the "service drop" (coax out to street)
home-run to your modem, and ONLY the modem. Wherever the wall plate
connections go (attic, basement, etc...) run a new coax from OTA antenna
to a splitter for TVs there.
Your TVs are probably using WIFI for the IPTV stuff (Netflix, Hulu,
etc..), if not drop an Ethernet cable there. You probably have that
part planned if you already "cut the cord".
You can't tie an OTA antenna to the cable companies' side of the
demarcation. No, you can't inject signal/noise on a live CATV wire!
Don't do that please. You'll get a visit from a cable technician rather
quickly if you do mess with their system. It is very finely tuned and
they (cable plant) takes extraordinary measures to prevent leakage. Many
trucks are equipped with "sniffers" that will log the location of leaks.
Your setup would definitely trigger their sensors in trucks and at the
head-end. The first one is free, with a warning. They will shut off
your service if you leak again, they get fined by the FCC for any

But he says he can stop anytime.
I don't know what the legal issues are regarding connecting a OTA signal to
the cable TV line, but in practical terms you'll end up degrading both
I have Comcast cable with my own purchased modem. Despite having Comcast
check my signal strength twice, I used to have a lot of issues with the
internet connection when the cable was also split to my TV's. Once I
dropped cable TV and ran a single connection to the cable modem, my signal
issues went away.
If you're no longer getting cable TV, I highly recommend running a direct
connection to your cable modem.
Then you can connect your OTA antenna to the old TV cables if you wish
(once they're disconnected from the cable company).
Your internet connection will be more stable and you'll get better TV
This will not work. Cable internet uses the same frequency range as TV
signals, they just grab an unused TV freq and use it for data. So, there is
not a diplexer that will have one port tuned to the internet freq and
another port tuned to all the rest of the TV freqs.
You are thinking of satellite TV diplexers, where the satellite TV freqs are
above the OTA TV freqs.

20 or 30 years ago i found out my neighbor must of done something similiar to the OPs idea. before the internet ......
anyhow one day my neighbor put up a new antenna, and got cable too,
shortly after this i found i could watch cable from my one tv. i even mentioned it to him, he didnt appear to care.
the quality wasnt perfect, but it was certinally watchable. then one day it ended when the neighbor moved:(
i missed cable so much i had it installed......
