Sorry, there was a problem. Please try again later.This antenna connects to the TV / receiver via 75 ohm coaxial cable. You can use it without the included amplifier or if you use the amplifier you need to an ac outlet to plug the USB power supply into. That is the only electrical connection required.
Sorry, there was a problem. Please try again later.This is an amplified antenna. It uses a power supply and a USB cable. If your tv has a usb connection on the back Of it you may use that for power to the antenna. If however you have more than one device hooked up to this antenna and the tv you are using for power to the antenna Is not on, it may not supply power for the antenna to be Amplified and thus the antenna does not work properly. I hope my answer is clear enough for all to understand What I am saying.
