Question: My TV only has a USB port for service.  Can this port be used to power the antenna?
Document: Or you can use the included AC power option (110V). I used the USB connection, just as I do with the Mohu. The amplifier has a green light to indicate it's working, on the opposite side of the USB port.
If, like me, the last time you used an indoor antenna it looked like a robotic rabbit you have got to try this out. I was able to pull in about 15 high quality channels by sticking this rather attractive looking antenna to my sliding glass window.Installation was a breeze. All you have to do is screw it into the cable slot of your television, make sure that the USB cable is plugged in to power the amplifier and away you go.
Winegard is using a small AC power block with a USB 2.0 cable attachment. This cord is a whopping 36&#34;. USB 2.0 specs allow for 16 ft max lengths. So we're safe in using a 6, 10 or 15 ft cable. Make sure you get a USB 2.0 Male-to-Male Type A to Type Mini-A (not Micro, thats's even smaller). This cable type is used with a lot of Tablets.
This antenna works really great for me. It pulls in more signals than any of the others I tried. I like that I can plug the USB power into the TV THAT's using it so the I'm not amplifying signals when the TV is off. The electricity is probably negligible but nevertheless I like to use as little as possible without thinking.
We live on top of a hill, so I doubt this antenna is working very hard to collect signals, but we get everything crystal clear. The two best features for me are the unobtrusive, piece-of-paper like shape and the USB power.It lays perfectly flat within the stand of our TV with the black side up so you never see it.
I used the supplied 110 power adapter and connected the FlatWave to the converter box and did a couple of channel scans. It found all the local channels. There were some I did not even know existed. After the Hawks game I stayed up half the night watching old Westerns on METV! My TV is in the front room and I don't have a window that faces east but it still works! Bottom line is that this antenna if phenomenal! And it has a very small foot print.
Pro: Clear, free HD channels - More than what I got with basic cable. Easy to install.Con: need to have a power outlet close (should have this since you have a TV installed). Or it will use a USB connection from the TV... don't like to give that up.
And this is at Lake Tahoe, where we used to have to subscribe to Cable TV as our only choice to watch television. I strongly recommend this product and am now saving hundreds of dollars a year in not paying for an exorbitant, lower quality Cable TV service.
USB is standardized, but I can't help but wonder if my TV was not putting out as much power as when I plug it directly to power with the adapter.Anyway, I hope it works for you as it did for me.Update, January 10, 2013:It has been almost a week. Here is the update. After I posted the initial reviews, I noticed big issues with NBC channel. I was getting a lot of pixelization and dropped audio. It basically made the channel unwatchable.
If this does not work for you, you need an external antenna. I have dealt with several indoor antennae incl. the rabbit ears that so many people are still in love with, but this is in a class of its own. Excellent signal, no artifacts and fed from USB port.
Answer: From the manual "If setting up the FlatWaveAmped antenna, connectthe mini coax cable to the"Antenna In" port as shownabove. Plug the mini USBinto the "USB PWR" portof the amplifier. Then,plug the regular USB intothe USB port of the TV orof the 110V adapter. Ifplugging the USB into the110V adapter, then plugthe 110V adapter into a110V outlet".  So give it a try and it will likely work fine.  Your antenna or TV WILL NOT have any risk of damage.
