This Cable Filter is meant for use on cable systems, when attached, it blocks the PPV signal that's sent to the cable company for billing. Your box will automatically give you the PPV event ordered once the order is placed but the filter will block the PPV signal from leaving the box, so legally you must alert your cable company of any "testing" your doing so that they can then bill you accordingly. If you are not a cable technician check with all laws before using this product.
