Forget what it's called..the device allows you to attatch it to the antenna and will send the signals in via Wi-Fi to my wireless gateway. Assuming I can then stream OTA signals to tv. I have a Roku Premiere+. What else if anything do I need and are there any other pieces (power injector, etc) does it come with? Keep in mind I'm using a preamp with a power injector and not sure how to wire it up. Thanks. Andy
