Test coaxial cable

Is there a way to test an in place coaxial cable ?

It provides cable service to 3 different points and some of the
channels at one point are fuzzy.

thanks.

You need better quality cable, or maybe an amplifier/splitter,

and 3 separate feeder cables(also of higher quality.).

Also first check the quality of the current tap points, if the
the cable impedance at those points is mismatched, your signal for the
upstream
points will degrade.

Odds are that the splitter or the branch cable that serves that point
is defective. inspect it, test the output of the splitter,
and start replacing bits unless the bill will be enough to justify
using a TDR other expensive tool.

probably something has leaked into, bitten into, crushed or
otherwise mangled the coax.

The most obvious answer here is to call the guy. If it's your own

installation, do you have access to both ends of the cable? Can
you borrow or rent or even buy a TDR or network analyzer or both?

(but, since you're a googlie, I don't expect you to see any of the
answers that get posted here.)

Good Luck!

I disconnected the coax cable and reconnected it.

Now all the channels are clear.

Maybe some corrosion had developed over time.

Just a note: Some of the cable companies are switching up to higher
frequencies, keep an eye on your splitter and distribution amp ratings.

I've just seen too many people posting from google and never being

heard from again.

Mint, I apologize if I hurt your feelings.

But, how are you doing on your cable thingie?

Thanks,
