The product description doesn't mention this (at least at the time of writing this article) but the bandwidth is only up to 1000MHz. It's good for many purposes, but if you need something for higher frequencies then you'll have to look elsewhere. However, if that suits your needs, these are great attenuators. Due to a weak signal in one of the farther rooms, I had to install a distribution amplifier in the house, but this made the closer rooms a bit hot. These attenuators are a better solution than adding an extra splitter that you don't need.
