Topband: plasma TV RFI?

Take your pick at this list:

or search www.mouser.com for capacitor 250vac

Since this  a 160 meter and higher application a .01uF disc 
would work,  but you have to be mindful of current that can 
pass through the reactance.

All of my TV and entertainment centers have a single common 
outlet strip like this one:

and

The older units I use have the CATV cable shield grounded to 
the center (ground) pin of the outlets. I replaced the small 
telco line fuses directly with small 100uH chokes any 
bypassed the line to common ground with .001 1kV discs on 
the equipment side only! The power line is bypassed from hot 
(small blade) to neutral (large blade, and then from neutral 
to safety ground with UL/CSA/VDE line rated .01uF 250VAC 
capacitors. The antenna cable feeding the center passes 
through the F connectors. Everything plugs in to the outlet 
strip. Speaker wires are bypassed to the neutral common at 
that box.

Not only does this stop TVI and modem RFI from my radios, it 
stops the TV, computer, and other gear from bothering the 
radios! As a side benefit there are a dozen or more hard 
strikes on my 300ft tower and have never lost a single 
device, not even a modem.
