Here is the surge protection that I like.  Double
the joule rating.  And an RFI rating.
Plus its a 12-outlet strip that includes
telephone and coax protection AND a second
6-outlet strip for $19.88.  The 6-outlet strip
includes some phone protection as well
as surge protection although not as much as the 12 outlet 
strip.

The important thing is the coaxial cable shield be grounded 
to the power line safety ground at the strip, either 
directly or through a capacitor, and the telco line be 
bypassed the same way on the load side of the chokes I add.

Any beads or common mode chokes are added on the power line 
or cable feed side of the common point, not on the equipment 
side.

This ensures all the equipment has a common RF "ground" 
point. Any currents flowing between the various lines 
arriving at the outlet strip will bypass the equipment, all 
the equipment floats at the same RF potential.
