It needs a power source. But can be toward the inside TV connection doesn’t need to be outside by the antenna location.
Sorry, there was a problem. Please try again later.There is only one connection at the antenna - the coaxial cable. But, the antenna needs (DC) power to operate properly. This power is supplied from a normal household power outlet by plugging the wall-wart into the outlet and the power-injector module. The power injector sends (DC) power to the antenna over the same coax that the antenna sends the amplified TV signal toward the TV.(s). I used a splitter to send signal to multiple TVs. The splitter had a path that was supposed to pass the DC power from one of the coaxial branches, to the antenna. I found that the system worked MUCH better, putting the power injector BETWEEN the splitter and the antenna, at the input to the splitter. Be sure to pay close attention the the labeling on the power injector, so it is inserted in the right direction. As a side note, this antenna is Bi-Directional. This means that it picks up signal much better in 2 directions than the the other two directions. Picture the antenna as a baseball bat. The ball can be hit off the front or back of the bat. But, you would have little success hitting a baseball if you used the bat like a pool stick. Hence, the front or back of the antenna should aim at the stations that you want to pick up. If the stations should happen to be at LESS than a 90 degree angle to each other, aim the FACE (front or back) of the antenna BETWEEN the two stations. If the stations are MORE than a 90 degree angle to each other, aim the END of the antenna (either end) BETWEEN the stations.
Sorry, there was a problem. Please try again later.Yes it needs a power source. But the power source is needed where it plugs into tv.
Sorry, there was a problem. Please try again later.Yes the small amp requires 12v
Sorry, there was a problem. Please try again later.It must have a power source to work. The power connector can be at the TV, it does not need to be outside at the antennae.
Sorry, there was a problem. Please try again later.A couple of weeks ago my cheap leaf style antenna stopped working. I was getting no signal. I was playing around with it today because a thunderstorm knocked out my internet. I decided to unplug and remove the ac plug that I thought was necessary for it to work. I simply unscrewed the antenna coax from the ac junction box and connected it directly to the TV and it's working again. I guess it's supposed to boost the signal but now, I'm getting no pixelization on some channels like before. Some channels were showing an error but after using the scan channels feature to program my Samsung it's working great and the picture is excellent. I just saved myself from purchasing another antenna and now have a backup if my internet streaming is not working or for local sports. Try it. I hope this helps.

I don't know why they have an ac adapter unless it's for those folks living further away from the signal but I am getting a better picture without it connected. I live about 30 miles from ATL.
Sorry, there was a problem. Please try again later.12 volts needed for amplifier ,I'm using a battery ,a power supply comes with the antenna
Sorry, there was a problem. Please try again later.It does come with a small signal amplifier that connects to the coaxial between the antenna and your TV which needs power. Usually not a problem plugging it in near your TV.
