The product came well recommended, and looks to offer excellent value for the price. It fit perfectly in place of the F-F grounding coupling in the entry box; installation took all of five minutes. Service was unaffected after installation; saw no significant signal loss per my DVR's diagnostic screen. Internet access and speed were unaffected.
The reason I'm not awarding five stars is a rather nasty surprise I received when reading the instruction booklet: it specifies use only with RG59 cable. It was in fact adamant on this point, specifying adapters (not included) on each side for use with RG6. The product description claims "It is specifically designed for todays Broadband signals carried over the coax cables." I know of no modern cable application that still uses RG59, including my own. I did not use adapters; have no idea what the implications are, but hoping it isn't a safety issue. Either way, this does not inspire 100% confidence in the product. At the very least, this limitation should be made clear in the product description.
So, five stars for the unit itself, minus one for the incomplete product description.
Installation instructions are here:
(replace the <dot> 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.Read more ›
After installing this, I noticed no degradation to either my cable television service or broadband speed. One of these days I will post photographs of my Data/Comm/TV distribution panel showing this device. Please check back in about a month.
Most CATV surge protectors are built into other surge protectors so I liked the idea of an independant unit like this. I have now used it for several months and not noticed any degradation in the signal at all. The signal I am referring to is a TV antenna being used for TV channels (digital) and FM stations (analog and digital). All my TV stations are coming thru without issues and all my FM stations are as well.
I also like the provisions for mounting the device on a board and easy grounding. Its surprising how many products overlook these simple features.
I have not had any surges so I cannot comment on this product's surge protection prowess.
