    Is this antenna directional? Is there a front and back?

      This antenna is an Omni Directional and will give you a 360 degree range. Keep in mind, although the range is 65 mile, it is in diameter.

    Great antenna 75 mostly clear channels.

    This antenna really works great. At first I was going to return it thinking it’s no good, I had a flat panel indoor antenna that picked up a lot more channels at first although not very strong signals. I found out through experience that with strong signal comes great tv viewing. Let me say I am new to this type of tv viewing. And I like it. So back to this antenna. When I first hooked it up I wasn’t impressed with it. I said it deserves a little more effort on my part to see it something is causing poor reception. So I’m thinking most of my stations are to the south and my antenna is facing to the north. Also my roof pitch is higher to the south. So I decided to raise the antenna 3 feet and then somewhat point it in the direction where I thought the towers were to the south and Bam. 75 mostly 5×5 signal strength Channels were found. It’s such a pleasure watching tv when it clear and audio is perfect. I haven’t even fine tuned this antenna. I have a signal strength meter on order when it comes in I will fine tune this antenna at a later date an who knows how many channels I will get. This is amazing how much free tv this antenna gets. This antenna may or may not give you the same results but make sure you at least try different arrangements for this antenna before you consider it junk in a review. It just might not be the right antenna for your situation, I was actually going to order another antenna until I experimented a little bit and now I am 100% happy with this one.

    Nice product for the money


    I mounted the antenna in our attic and was able to go from 4 channels with a window antenna to 26 with this one. I now receive all of my locals (which was the goal). By looking at the map the range is impacted by line of sight issues (mountains), but this is to be expected. I don’t think the next model up (AT-414b) would have actually worked any better. I am happy with the purchase. The install can be as simple or difficult as you make it.

    Small and works well


    I got sick of the thin window antennas in our house and mounted this antenna up on my chimney. The old antennas needed to be in the perfect spot and were an eye sore. This new antenna is great. I live less than 10 miles from a major metropolitan area and reception is perfect, without turning the amplifier on. I love that this antenna is small.

    It feels like it weighs less than a pound and I secured it to my chimney with Tapcon anchors. I then wired it to my living room and basement TVs. I didn’t even have to reset the channels, it just worked.

    Of note, whether you turn the amplifier on or not, it must be plugged in. I found this out after installation.
