Does anyone make a plug in suppressor that has TWO coax connections? I
just realized that I was considering running both cable and an antenna
connection to each TV in my house, but all the surge strips that I have
everything connected to only have connections for one coax (I guess
they assumed that someone would have either cable or an antenna but not
both...)

I haven't seen one. You really should be doing your coax surge
suppression at the point of entry for both your feeds. There are in-line
F connector surge suppressers that install quite nicely at the ground
block outside the house.

I had a couple cable modems blown up by nearby lightning strikes shortly
after I moved here. I drove a new ground rod, connected a ground block
to it with a short wire and installed the in-line suppressers at the
ground block. Since this installation I've had plenty more nearby
lightning strikes, but haven't lost any more cable modems or other
equipment. I don't use any additional coax suppressers in the house
either.


An odd thing happened when we installed a coax suppressor. This was in a
new home with a new Cox coax feed. Our cable modem worked fine, but we
lost about half the cable stations from our cable box to TV. It was not a
channel filter. Cox advised us to remove it, and all channels were back.
I haven't tried another suppressor.

Possibly the suppresser didn't have enough bandwidth to handle the
higher frequency channels without too much loss? Been a long time since
I worked for Cox in CT, so I'm not sure what they're up to these days.
The two Leviton inline suppressers I used here (from Depot) on my cable
feeds have not caused any issues with any of my cable channels.
