Hi Jim,
The filter is in a metal enclosure with a short power cable, about 1 foot 
long that plugs into the computer power connector, and another power cable 
about 5 feet long that I have plugged into a power strip which is used for 
other equipment in the shack.  Could not have been simpler.
My purchase was made from Array Solutions, and you should be able to find 
the information you need at their website, 
http://www.arraysolutions.com/Products/nqnaclinefilter.htm .
In my case I had a problem with interference from the computer, and not sure 
if this would help if you are having a problem with something coming from 
the RV park power lines.

GL & 73,
Tim - N3XX
