Re: [HSI] What about an in-line coax surge protector?
Typically, the CABLECO does put in a surge protector / ground block on new installations. This became fairly common practice about 15 years ago. Some are simple MOV's or even shunting SCR's.
The first, and most important, thing to check for with a CATV installation is that it is properly bonded / grounded. It should never be on an individual ground rod. It always be bonded to the power ground (along with phone, satellite, and other systems).
If this is done correctly, then you should move on to adding an SPD. Personally, I like SPD's to be mounted outside the dwelling / structure, but code does not specify where the SPD is located.
I've seen lightning do some wicked things to coax. (I used to be a "cable guy", then a "phone man", and now a master electrician). I've seen it vaporize the coax all the way to the GB and not even touch the inside. I've seen drops where the only thing left was the center-conductor. Unfortunately I've seen it blow every single connected device as well.
When it comes to lightning, we can only make "suggestions" to it, and hope it follows them. When it comes to direct hits or surges from very nearby strikes, you're often just SOL.
