It is specifically designed for todays Broadband signals carried over the coax cables. Review: Far superior to the "block" used by most - First off, I did some research on this device long before I purchased it. The data sheet from the manufacturer is available here: tiinetworktechnologiescom/repository/datasheetlibrary/NYMDS036-0710pdf Installation instructions are here: tiinetworktechnologiescom/repository/installationsheetlibrary/92219901-tii_210&212_InstNtpdf (replace the with a period to complete the URL.) It should be noted that there is a shock hazard if this device is not installed inside a listed indoor/outdoor enclosure. This does not say it won't work, only that you might be exposing yourself to a shock hazard. I simply installed the block in a protected location that is out of the direct weather and not likely to be touched by humans (on a joist under a covered porch). Three very important characteristics apply to this device: 1) It protects surge from both the shield AND the center conductor. The standard 'block' does not protect the center conductor. 2) Automatically resets. A couple other devices on the market will shunt to ground, but then are done. While the amount of energy dissipated matters (see the data sheet), this device can reset and provide service more than once. 3) Can conduct power. If you use a pre-amp on your antenna or your cable service needs a powered feed to the distribution box, that power will still flow through the coax and this device. It should be noted that the specifications do indicate a signal loss of roughly 0.2db (they guarantee < 0.3), so some signal will be lost from this device. However, this loss is minimal, and typically less than many cable to cable couplers will cause. Of course, there is no way to determine if the product works unless I get an electrical spike, but short of erecting a dedicated lighting rod, this is about the best you can get. In practice, I found the device easy to install, create minimal interference, and resulted in a piece of mind that I'd done all I could to protect my investment.

The cable guy claims lightening is a bigger issue with underground lines than aerial. A few years ago, I installed this lightening arrestor inside the cable box on the outside of the house and grounded it to the electrical meter grounding rod. It's very important to connect to a good earth ground. Since then, no more damage. I do not ground the coax cable inside the house. But, the power cord to the modem and router are through an APC battery back-up with 50,000 volt surge protection. That's important, because surge damage can sneak through the power line side, too. If you have frequent thunder storms, you may consider changing this device out every few years. Basically it's a spark gap device. When the voltage exceeds a threshold, it jumps the spark gap to ground. But, every time it does that, the gap gets a little wider. Over time, the protection voltage rises depending on how many times a spark has jumped the gap. **Q: I'm planning on installing these in-line with a terrestrial over-the-air antenna system that is mounted on a mast high above my house. I also have a mast mounted pre-amplifier near the feed point of the antenna system, which is powered by a DC power injector in the attic of my house where it enters my internal distribu…** A: Mine works with an old Radio Shack pre-amp. 6 years later I got hit by lightning , blew the electric meter , blew both line fuses at each end of my power line, 1100 volt line, killed a big pine tree by my house. Then my tv would not receive signal. This protector shorted to ground I guess because the pre-amp power source inside the house led would not light up when connected to the antenna feed line. So put a new protector in and problem solved. Did not even have to replace the mast mounted amplifier. They don't build pre-amps like they used to or I got lucky. But that is how my protector made me aware it was defective. **Q: Does this surge protector, when properly grounded, also serve as a grounding block for a TV antenna?** A: The antenna itself must be grounded separately. There are many websites which describe how to do it. The TII 212 Broadband Cable TV ground device only grounds the coaxial cable. **Q: what gauge bare copper wire will this unit take?** A: From the manufacturers website for the Series 212 which is what this is: Strip and insert a #12 (minimum) ground wire into the hole provided on the surge protector. (Figure 3-1). Turn screw until wire is compressed and tight connection is made.See page 2 on the installations instructions on the following link. Once again, it is the Series 212:http://tiitech.com/repository/installationsheetlibrary/92219901-tii_210&212_InstNt.pdfAlso as far as the operation of the device if you have RG59 coaxial cable, you may need to change to RG6 coaxial cable "to ensure proper operation" of the TII 212. "Suitable adapters must be used that have center pin conforming to .040 inches requirement (eg. RG6, RG11)." ## Customer Reviews ### ⭐⭐⭐⭐⭐ Far superior to the "block" used by most *by C***O on October 10, 2013* First off, I did some research on this device long before I purchased it.

Old coax power strip surge suppressor started malfunctioning cutting antenna signal periodically. Recently purchased a new VT30 65" Panasonic 3D Plasma as well as new Onkyo TXNR 709 receiver so figured that I would replace surge unit on antenna coax cable coming into house. Living in San Diego-really don't see much lightning-but you never know. There really is no way to check operation or performance of this unit without a lightning strike. You of course are hoping that lightning does NOT strike your antenna-to find out if it actually works LOL. Previously had a coax grounding block on line coming in outside & in addition to the power strip coax surge suppressor in the house that was malfunctioning. This resembles one of them(the outside coax grounding block) but it has a little more to it than just a simple pass through like a ground block has. My biggest initial concern ordering it was based on a few reviews that it may degrade antenna signal strength. Signal is boosted with an antenna booster already. The addition of this device did not appear to reduce antenna signal strength- once installed. Unit appears to be well made, will it work? Who knows. I will eventually add a new-in the house UPS with coax surge suppressor to replace the current UPS I have now that does NOT have coax surge suppression on the unit. Unit is reasonable priced & is probably useful to have in case of lightning strike or even static charges on line. Having redundant protection is always good when your protecting thousands of dollars tied up in HDTV & high end receiver. Considering the cost-it really is a no brainer. ## Frequently Bought Together - TII 212 Broadband Cable TV and Satellite Lightning Surge Protector 75 Ohm 5-1500MHz, Modem - Televes DATBOSS LR Mix Hi-VHF UHF Long Range Antenna with 5G Filter 75 Mile Range 149884 - 50ft Quad Shield Solid Copper 3GHZ RG-6 Coaxial Cable 75 Ohm (DIRECTV Satellite TV or Broadband Internet) Anti Corrosion Brass Connector RG6 Fittings Assembled in USA by PHAT SATELLITE INTL --- ## 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.com.ar/products/1867496-tii-212-broadband-cable-tv-and-satellite-lightning-surge-protector](https://www.desertcart.com.ar/products/1867496-tii-212-broadband-cable-tv-and-satellite-lightning-surge-protector) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-27*
