How Long can you run Coaxial Cable?

How far does it have to run to be too far? Ive had this since 2006 but after reading that the longer the cable the worse it can be I`m kinda worried.

I know its not a good pic, (maybe 50ft?) But the Drop runs from that power line and into a grounded coupler thats on the side of the house and then another maybe 30-40 foot up to go into the house (upstairs) and Directly into the cable modem. is that good or way to far?

Companies typically say 250ft for rg6 and 350ft for rg11 from pole to splitter/ground.

Your signals are fine, you could probably go another 350ft and still be under -10 for receive.

Average drops in my town are about 120ft.

Thanks! Does a Coupler hurt anything? there is one outside that is grounded that connected the wire coming from the power line inside, and then another one inside connecting to a 6 foot coaxial line as I needed to extend it.

Cable Company is coming out tommrow as I asked if they could just cut me some new Coax but not sure if they will

Technically, the coupler does introduce a very small amount of signal loss in the line, but nothing that you would need to be concerned about. I once saw a contractor do a 150' run with barrels and 6 foot pre made jumpers.

The drop to your house is extremely short. Most are much longer.
