Cable Broadband Surge Suppressor's - shopping for - are they worth it?

[durangod]

Hi,

Years ago i lived out in the country and we had a lightning strike and it fried my ethernet card as the surge went through the cable internet line. The cable company finally reinbursed me for a new card because the tech that came out to look at the line told me that the first tech had never grounded the line in the box, that issue was fixed.

So now years later the cable company in my new place is offering me a sweet deal on broadband. The most i can get with my DSL is 12MBPS, and the cable company is offering me 100MBPS for about the same price which is great.

However if i get cable again i want to get a Suppressor unit, something like this.

however im not sure what i should be looking for in specs, are there diff kinds, protection ratings and that sort of thing.

Does anyone know about these things and are they worth the money?
Is this something i should tell the cable tech to install on the line for me?

The ISP should have a grounded supressor on the "demark" (where their cable first comes into the house). Just make sure the ISP grounds it like they should.

What you linked online would provide an extra safty layer, but you have to ground them to your grounding rod or to a copper pipe, just connecting the coax to it will not do much because the extra current has to go somewhere. If you wanted to do the ISP one AND one you purchased I would go with this one so it is easier to mount with your ground wire: https://www.amazon.com/TII-Broadband-Cable-Lightning-Protector/dp/B0016AIYU6/ref=pd_cp_23_1?_encoding=UTF8&psc=1&refRID=V8EN2GXEK2R1HTMXYNBQ

Thanks Boosted1g, how deep does the copper rod have to go into the ground, do you know?

Something like 20 feet. Your home should already have a grounding rod for your electrical system. So grounding through your electrical system should go to the rod.
