Note that the above reviews are of the Gutwire Maxcon, there is a newer version called the Maxcon2 (squared, not two.)
They also make excellent power cords, they work in combination with the filter.
The filter is passive.
The unit can be bought on line at UHF magazine. (in Canadian funds, as well.)

You might like to know that UHF uses this filter in their reference system (if you are not too familiar with UHF magazine, they are known for not recommending anything that doesn't pass their three person review panel. They will also give all the facts, good or otherwise.)
