Bearing in mind what Mark said, it might be better to use a multiplexer
than a splitter. Despite the fancy 4-syllable name, they're very cheap
too. As well as the antenna amp, of course.

Even without that, I find it hard to believe the puny signal that comes
out of a cable box will radiate even to next door from an antenna. Do
you remember the Subject of that thread?

The FCC says otherwise:

https://www.fcc.gov/guides/cable-signal-leakage

This is a general warning and says NOTHING about antennas as a source of
leakage, and thus it says nothing about using an antenna amp to block
the cable signal from going up to the antenna.



"Cable signal leaks occur when the RF signals transmitted within a cable system are not properly contained within the cable plant. Cable signal leaks can be caused by loose connectors, damaged plant and cracked or unterminated cables."

Yeah, that was there, for sure. By golly, I remember reading it! I
even remember quoting it!!!

And I cited the FCC based on your recommendation to just use a splitter
to combine the antenna and cable:

"maybe you can just connect both the cable and the antenna with a $2-5 splitter (a joiner connected backwards) and I think their signals are on separate frequencies that won't interfere with each other. "

After listing loose connectors, cracked, un-terminated cables, you think
the FCC has to specifically say "don't connect an antenna to the cable"?

Absolutely. That's an entirely different beast from loose or cracked,
which are physical defects. Unteminated is a third kind of beast.

Just how stupid are you?

Smarter than you, it seems.


Obviously not if you can't fathom that if a loose connector or cracked
cable can radiate the cable signal to the neighborhood, then connecting
an antenna would be even worse. I guess it's for guys like you that
they have to put the 6 pages of warnings on power tools and appliances.
They could say, "Warning, this tool has sharp pointed edges", but if they
didn't tell you to not put it in your eye, you couldn't figure that out. And
then after you put your eye out, you'd sue them, saying it's all their
fault, they should have.


I didn't comment on your suggestion to use an antenna amplifier for isolation.
I didn't see the need to, because as I pointed out, you're solving a problem
that doesn't exist.

Baloney. Then why did you comment on the rest of it?

Because you recommended combining the cable system with an antenna
using a $2 splitter. I commented on why that's a bad idea.



Why did you write "The FCC says otherwise:
https://www.fcc.gov/guides/cable-signal-leakage" If the antenna amp is
moot now, what the FCC is just as moot.


No it's not, it still applies to your first recommendation, which was
to use a $2 splitter. And while adding an antenna amp will prevent
the antenna from radiating the cable signals, it too is a bad idea because
there typically are shared frequencies between cable and OTA. So,
while it won't spew signals, it probably won't work either. But you're
right that's a moot point, because the poster clearly stated his issue
was in the past and he had REPLACED CABLE WITH DIRECT TV.



The poster doesn't have a problem. He reported that he
no longer even has cable, he's switched to DirectTV.

By golly, he did.


There you go.
