Should I splice this?
Connecting my roof satellite and found one of the coax cable chewed. Should I cut this out and splice it or should it be good to just wrap with electrical tape?

I would wrap it good, putting a splice in COAX will cause signal loss.

From the looks of that coax, much of the shielding is gone in several places. That will cause more signal degradation than a quality splice connector.

if the shield is intact I'd just wrap it with electrical tape. Sheath is only for insulation

I would splice it, it is acting like a big antenna right now. I would use good quality ends and a barrel connector.

Looks like the dielectric center insulator is damaged in a few places. If that's the case, then the damage should be trimmed out and spliced if there's enough slack. If there's not enough slack then either pull new cable from one end to damage free cable and splice it.
Of course the best fix would be to pull completely new cable end to end.

X2. Replace the entire cable.

I would prefer to change it out but I’m really nervous about trying to pull through new cable. Do any of you know if I can depend on it not snagging up?
The metal sheathing is not broken but the little metal wires (that like to poke your fingers) are missing on one half.

You can wrap with aluminum foil and then seal with electrical tape.

Looks like just the outer insulator has been eaten. Wrap it with tape connect the TV and see how it works. (my money says just fine)
You likely have 2 or more right angle turns to make to pull a new cable between point A and B and perhaps a staple or two holding it in place before the walls/ceiling were closed up.

Could have been damaged during installation. If the top area is showing foil then the coax is a quad RG6 cable and there would be another wrap of shielding under the foil. Anyway just the outer insulator appears to be damaged (can't see the conductor) so I think taping would be sufficient; it would certainly be easier. Don't know how much of an EMI problem exists on our units. As said, tape it, try it.

I would splice it . Splice only looses a half DB , tv won't notice it . Make sure to get the correct connectors ! If it's quad shield or not .

A cable guy with the right connectors and tools would only loose a 1/2DB.
Since it looks like the foil and certainly the inner conductor are unharmed and the entire run can't be more than 40 feet he'll never notice a signal loss if he just tapes it and goes don't you agree?

Depends whether water has gotten into the braid or farther . If your not having problems with reception , tape it up real good .

Don't make it harder than it needs to be.

Agree with with Redboat. It looks like you may have a rodent (mice or rats) problem from the looks of things. Ants are also known to eat on cables too.

Depending on how severely and where on the cable the shield is damaged, you can get resonances that have many dBs of loss. Best to install the correct connectors and a high quality barrel. It's not hard to do and the connectors and crimper are readily available.

Does TV work?
I would base the decision to splice or tape on whether the TV receives a good signal right now. If normally received stations still work, then I’d just tape it.

My 2cents replace why worry or worse have a issue later.
