Does this need to be powered in any way by itself or just connect the cable and you are good to go?

Good to go unless you get a preamplifier (highly recommended), which does require a power source.

I just connected it to the tv. Since this is used at a vacation home, I didn't mount it outside, I just put it on top of a large box by the window. Although we don't get all the channels, the ones we do get come in pretty clear.

Power not required. I suspect if you live far enough away from the source, or you split it aggressively, you might need a powered signal booster, but for us the signal is outstanding when split to two TVs, no power boost.

Where I live I was able to just connect to the cable and that was it. No additional power. Some reviews said they needed an amplifier others said an amp made reception worse. I guess it all depends on your location.

I just connected to the cable and was good to go. Older TV's need a converter box.

Just connect the cable and go, I am a 55 year old woman and I installed this myself. Very easy.

You CAN power it up via the USB Port OR the external Power Adapter. Using the external Power Adapter allows the plugged in( tested or augmenting) hard drive to operate more efficiently, It's another step but worth the small effort. Product support recommend connecting it that way... so that's what I did. If you do likewise you should connect the Power Adapter BEFORE connecting the USB Cable.

HI, it's powered itself. you just need to buy the set of wires to connect it to the stereo.

No. This is totally portable. No external power needed. It will not charge devices it is just a hub which is exactly what I wanted. It works terrific.

No you've gotta use your own charger cable. It is easily accessible though.

I'm not sure what you're asking here. The cable not is powered; it simply connects directly from my HDMI device(PS3), to a monitor, both of which are powered themselves.

It is powered by the USB connection and doesn't require an additional power supply. It is not wireless and must be connected with the USB cable.

Steven it is USB powered but comes with a second USB cable to provide extra power if required. In my experience it seems to be needed. Regards John Docherty.

If your TV has a USB port, the antenna is powered by it. No other power source is needed.

No, it will need to get power from USB cable. Meanwhile, it will also need to get signal and drawing through computer's support.

It must be plugged in. The resistance is independently powered - meaning: not a generator.

No, although the directions in the box say to connect it, you do NOT need to. There is no difference when you plug It in or keep it out.

Yes, it will power itself from the adapter when plugged in and from the battery when it is not.

You don't need to. For the starter kit purpose there is a USB cable that will power the board from your computer when connected. However if you want to run the board and not have it connected to your computer than you will need a power supply.
