There are a lot of different DB's ratio for this connector. So far the 12db connector has worked the best on my Tivo's. I have bought other db's in this connector just to have if every needed. ### ⭐⭐⭐⭐⭐ One-Trick TiVO Pony *by P***C on Reviewed in the United States on April 22, 2013* This little adapter reduces the signal power on your cable (coax) line. Why would you want to do that? Usually you worry about having too little signal, not too much. It turns out that modern TiVO devices are allergic to unusually high signal strength, and they pretty much go haywire when they record that - the signal seems to be jumping back and forth as if you'd been playing with the fast-forward/rewind buttons. Very mysterious (and bad design on TiVO's part, I suppose).How do you end up with excessive signal strength? Ask your cable company to sell you (truly) high speed Internet, and they'll put it on the same cable as your TV signal. Then they'll boost the power to 11 to make sure your Internet signal makes it through, and the boost also applies to your TV. Voilà... trouble.An adapter of this kind will solve your specific TiVO-vs-Internet problem just fine - if you get the right amount of attenuation. To little and you'll still have trouble. Too much and you'll start seeing decoder artifacts. Keep in mind that a few dB (decibels) go a long way. In our case, 12dB was too much, and 6dB was just right. Your mileage will vary; just buy a set of varying strengths and try them out until you get the right one. (Yes, you can stack them together.)5 stars for these adapters; a subdued hiss-and-boo to TiVO for making them necessary.Cheers -- perry ### ⭐⭐⭐⭐⭐ Fixed the sound loss/pixelation problem with my TiVo HD and Comcast Cable *by W***R on Reviewed in the United States on March 12, 2014* My TiVo HD worked perfectly with my Comcast cable (with a CableCard) from 2008 until September 2013. Then suddenly I had frequent audio loss and pixelation issues (at least twice an hour during live or recorded shows). I tried different CableCards and had Comcast techs come out multiple times. They replaced cables and ran tests. They said that the cable was functioning correctly. I was sure my TiVo wasn't failing, since it seemed to work properly in every other respect; so I refused to try Comcast's DVR for some time. After a while I had to try Comcast's DVR in place of my TiVo HD to prove to the Comcast techs that my TiVo HD wasn't the problem. Of course the Comcast DVR worked perfectly! I was at the end of my rope when TiVo tech support (finally, after multiple e-mails!) suggested an attenuator. I looked them up on amazon and saw that these attenuators had solved similar problems for others. I'm so grateful that these others posted this information. This In-Line Coax Cable TV Signal 12 dB Attenuator seems to have solved my problem, no sound loss, no pixelation, for the last few days. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/13279877-parts-express-in-line-coac-cable-tv-signal-attenuator-12](https://www.desertcart.jp/products/13279877-parts-express-in-line-coac-cable-tv-signal-attenuator-12) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-03*
