   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/NYMDS036-0710pdfInstallation 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.

   Finally got around to installing this, after it sat on my shelf for three years. Whole project took about 30-minutes.- I didn’t realize the Cable Company already installed a ground, so it was just a question of replacing their ground with this ground.- I tested Internet speed before & after (four tests before/four tests after) and it was not changed at all. TV still works good.- As of today, it’s exposed to the elements on an exterior brick wall. Ordered a cover & clamps today, looks like that’s another quick project.Tools used:- I was able to re-use the existing ground wire. That required a Philips screw driver.- The screws on the existing ground were twice as long as those that came with this suppressor, so I re-used them. Flat head screw driver.- This suppressor is about 2″ longer than the existing ground, which kinked the cable towards the service side. It took an impact-style head to unscrew the existing cable-clamp, even out the slack, then re-tighten the clamp.Don’t know how effective it is, yet. But I’ve spent a lot of time reading through the reviews of people who know more than me. They assure me that this type of suppressor is WAY more effective than the MOV-type that comes with my UPS. Between my modem, pfSense firewall/router appliance, and WAP, I’ve got about $600 of equipment in sequence on this line. Not to mention the TV. Good peace of mind.Well worth $17 and 30-minutes!Really appreciate the other reviews & the people who took the time to answer questions.

   Picked this up from Amazon couple weeks ago. 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.
