Here's a little HDTV antennas 101 for those who are new to these devices. There are HDTV digital signals in the air - available to everyone for free.

Generally, they include the big 3 (ABC, NBC, CBS) and others. The only issue is how to capture them.

Most TVs don't have a strong enough internal antenna to receive them well. That's where HDTV antennas come in.

There are other things that come into play like where the transmitting towers are located and how far away they are.

Also where you place the antenna in your home makes a huge difference - in or near a window usually gives the best possible reception but that isn't always possible. You can even buy outdoor HDTV antennas.

In general, people living in and around large cities will pick up the largest number of over the air channels.

People living in very rural areas will have the most challenges picking up strong over the air signals and should probably choose an antenna that has the longest range and can be mounted high and outdoors.

There are passive HDTV antennas, like this one, which have no additional amplification. These are best for people living relatively near signal towers.

Then there are amplified antennas, which boost reception and help to pick up weaker signals. These are very helpful for people in rural areas or people with a lot of interference around their homes.

One of the biggest reasons people look to HDTV antennas is to cut their cable service.

If you are someone who doesn't watch much broadcast TV and supplement with streaming devices like ROKU, cutting out your cable TV service completely may be a great option for you. Also, people buy antennas for TVs in rooms where there is no cable access.

So this particular HDTV antenna from 1byone is a flexible, flat panel window antenna that is rated for a 35 mile range. It's mostly a clear, flexible panel with the antenna wires covered in an unobtrusive beige material.

It measures 13" long x 9" tall and when mounted to your window, it doesn't block the light coming through. It attaches via two, clear suction cups and they work very well.

I like this better than tape or adhesive because it's easy to move around until you get the best signal possible.

Set up is easy. Connect the included 20ft. coax cable to your HDTV and the back of the antenna. Place the antenna in a window.

Turn your TV on and in the setup menu, perform a channel scan, making sure it is set to "Antenna" or "Air". If it is set to "Cable", you won't find anything.

I would suggest going to antennaweb dot org and plugging in your address or just your zip code.

It will show you where the signal towers are located so you can place your antenna in a window (or on a wall) that will get the best possible reception.

After the scan, if you aren't happy with the number of channels or the signal strength you have, try moving the antenna to a different window and/or higher up on your window, if possible, and then run the channel scan again.

Remember, every time you move the antenna, you must run the channel scan again. It may take some time initially to find the best window and the best position for the antenna, but after that you'll be pulling in free HD broadcast programming!

If you are getting weak signals, you can buy an optional amplifier to boost signal strength. Understand that an amplifier will only boost signals that are already within range. It will not create new signals.

I live in a large city so the first window I put this antenna in picked up 37 channels with great quality.

Moving the antenna to a different window gave me even more channels! You can place this antenna on a wall and if you live in an area with strong signals, this will work fine.

My son has a window antenna that he has placed on the wall next to a sliding glass door and the reception is excellent.

One thing to note is that this set up is for HDTVs. If you have an older, huge tube TV, you will need a digital TV converter box.

This antenna is best for people who live in or fairly near a city with broadcast towers. If you live in a rural area or one with a lot of obstructions surrounding your home, you might want to look at an amplified antenna with a 50 mile range instead or perhaps an outdoor mounted antenna. 1byone makes a wide range of exceptional antennas.

For smarter people than me, here are the specs for this particular antenna:
Frequency Range: 47-230MHz, 470-862MHz
Receiving Range: FM/VHF/UHF
Gain Max: 6~8dB
Out Impedance: 75'
