I bought this HD antenna because many months ago I released the cable tv and I needed an antenna for when I lack the internet in the house to have something safe with which to see local channels in both English and Spanish. With this antenna I grab enough channels at the rate of 65. Most of them in SD but I also have several in HD. This antenna can be placed in a window as well as on a wall according to the best reception in the place of installation. It has an amplifier which is connected to a USB port of the same TV and also the normal connection of the antenna that is connected in the back of the TV. It has a cable long enough to be able to change its position as well as bring stickers with glue.
