Yes the filters work, but not to prevent interference between modems and boxes.
Mostly that filter will kill the 2-way communication needed to order VOD and keep the box working during periodic polling. |

Worth about $1 to $3
Cable modems do not interfere with boxes. Dumbest thing ever claimed. |

Yeah, it works exactly like they claim. If your modem was pushing out any interference on the return band, that filter would do what they said. What they don't tell you is that cable modems return path does not interfere with your box and that not only is it going to block the return signal "interference" it is also going to block the return signal of your box, which is used for VOD.
They also sell those filters with the pretense that you can get free PPV with it because it blocks the box from sending the billing info to the cable company. The problem with that is that the box saves all of the PPV info until it is sent to the headend. Once you turn the box in, the PPV info gets sent once they plug it in at the warehouse, so your PPV bill comes all at once.
It makes me laugh when I think about how many people throw their money away on ebay buying filters and stolen boxes. They will spend anywhere from $5-$250 to get something for free, and it usually ends up costing them more that what they would have paid for. |
