I haven't had a cable TV for the last several years since I found my family didn't need so many (too many) channels and could watch handful of channels for free through antenna. It's called OTA (over the air) channels. You may have to give up some of your favorite channels (I personally miss the Discovery and Family channels) from the cable TV providers, but it's FREE!!  Depending on your location and orientation of the antenna, you could get several to over 30 channels.

There are commercial products both indoor and outdoor.  The outdoor antennas certainly work (much) better than indoor antennas because their elevation from the ground is high so they can catch more signals and there is no obstacles such as wall or house structures compared to the indoor antennas.

But the indoor antennas have their own benefits: 1) you don't have to climb up the roof to install and maintain it; 2) you don't have to worry about thunder or lightening; 3) it's relatively cheaper than outdoor ones because it doesn't need long cable and fixture material.

So, as long as your location is in or near urban area and you have a proper spot inside your house to put it and want to create your own antenna with various shapes and sizes, give an indoor FREE TV antenna a try!

Here is my version.

The aluminum foil in the kitchen is always handy. I needed a support to attach two pieces of aluminum foil and found a piece of cardboard box. The size of each side of the aluminum foil is 250mm x 215mm. I didn’t test other than this size but it works good enough. You may want to try different size and shape of similar design for your TV. I could get over 20 channels with this.

Step 1: previous version

I moved to this new house a few months ago and as soon as we moved in, I quickly made this antenna.

I found this TV antenna design from internet some time ago and it really works quite well. A matching transformer in the middle in this picture is missing since I have already removed it to a new design. This one works fine but I don’t want to put this one on top of the roof because I don’t want to take any risk of thunder or even climbing up to the roof, nor to hang it on the living room wall because it is not that small (about 1m high) and doesn’t look pretty. So I decided to test very simple antenna that is cheap, small enough to be hidden behind a picture frame, and indoor.
Can i made it without using transfomer
I have tried once without the transformer and it still worked for those channels that their stations are close to my place.
<p>Its really amazing but i feel those will not help with better quality and clearance. YuppTV, which is offering the Indian TV Channels includes <a href="http://tamiltvchannelsnetherlands.blogspot.com/2016/05/Tamil-TV-Channels-Netherlands.html" rel="nofollow">Tamil TV Channels</a> also needed when we are in abroad to watch our favorite Tamil TV Show.</p>
<p>Do the 250 mm edges or the 215 mm edges face each other at the gap?</p>
<p>That's 215mm edge. </p>
<p>To improve my signal reception for my OTA antenna. I went to Walmart and bought ($15) an RCA amplifier and now I get 65 (TampaBay FL) Channels. 5 months now and I don't miss paying that monthly fee to my carrier.</p>
<p>I have some RF cables, could I use these instead of the Balun? The RF cable is the cable with the single copper wire in the middle, it screws onto it's connector. I have some alligator clips to aid the construction.</p>
<p>Oh and what channels do you recieve?</p>
<p>I have about 27 channels including some shopping channels. The most strong signal channels are 2-1, 2-2, 4-1, 7-1, 7-2, 9-1, 11-1, 11-2, 20-1, 50-1, 56-1, 56-2, 56-3, 62-1, 62-2.</p>
<p>cool, oh and I tried it with the Coax cable, I got 28 channels with a smaller antenna (I probably live close to several stations).</p>
<p>The RF cable is just a coaxial wire. As you said, the core wire and shield outside. The Balun is, on the other hand, a type of transformer. The antenna inlet on a TV and this type of home made antenna has different impedance and they are not balanced. That's why you need a balancer (a.k.a. Balun). So you will need a Balun. However, I would try without a balun. Depending on how close your location is to those towers, I'm sure you can get some channels. Give it a try without one.</p>
Sir, i didnt find matching transformer in my area. What can i do. Can i try without that. Pls suggest me.
I have tried before without the transformer and it worked, but less channels. It depends on how your location is close to those towers. So give it a try. Good luck.
<p>I used your antenna on my scanner. It improved my scanner range by 52% . Thank you so much. I will try any thing once</p>
<p>I'm glad my Instructable helps someone. But what scanner did you mean? TV channel scanner maybe? </p>
Thank you so much. I have been trying to increase the range on my scanner for years now but nothing worked. So I took a chance with your antenna and it works fantastic. So it dose not just work on TV.'s
<p>I'm getting ready to &quot;cut the cord&quot; and this design is simple and very well done! How far are you from a tower? I'm between 25-50 miles from at least five towers but curious if i'll reach any. Also, do you believe a matching transformer would work just as well with this design or should I order a TV Impedance like you did? </p>
<p>I don't know how far my house is from those towers, but 25-50miles sounds a little too far to me. I would do some test first before cutting the cord if you meant your cable. Just unplug the cable from the back of you TV and insert a wire (20-24 gauge) on the antenna plug center core. The longer the higher the better. If you can get at least a few good signal with it, you are good to go. Regarding the matching transformer, if you have one handy already, give it a try. I think it will work. Good luck and enjoy!!</p>
Thanks for the reply. I should be attempting this this week and will return with results. Thanks again.
does it work in other countries I mean in india??
<p>If the digital TV frequency in India is the same range as in North America, it will work.</p>
ok thanks man but I don't know about this frecvansy of India or NA... can you please upload videos of making progress please
Sorry I didn't make any video for this Instructable. The pictures shown in these steps are all I have. Regarding the frequencies in your country, I don't know either. Try Wikipedia or Google.
if you find more about this type project please share or I wish there is one video for making this it's help me
Is it possible to work in Indian T v
I think it will work, but I'm not sure.
bro I am interested in this type of antenna. how can I spend money for antenna
<p>not sure why you cut the coax, if you bought the balun, you could have bought a splitter. The way you did it will mess with the 50 ohm impedance of the coax. Your signal would improve with the splitter.</p>
Well, as of today, I have 26 channels with this antenna, so I'm satisfied and not planning any improvement at this moment. Thanks for your comment.
<p>would love to see an nec2 simulation of it.</p>
Awesome! Congratulations. <br> <br>You would redo the union in step 4, these coaxial cables require the outer mesh lead be always around the inner. As you did, the inner cable could receive interferences (athmospheric or house) in that joint.
Thank you for your comment and that's exactly why I wrapped the shield cable with the foil.
<p>size of the wire top of the cardboard? please</p>
<p>That's 22 gauge.</p>
Forgive me, I did not see that.
This is nice, I also like the profile of your antenna design. Thanks for the share.
Thanks!
Great antenna, thank you very much for this simple design. I can use it in many situations if a quick one is needed that I can make out of scrap
Thanks!
It es pragmatic an great. To transfer this idea with other frequencies, especially the wlan 2.4 GHz, what are the TV frequencies for this antenna ? MfG Melibokus
The channels I got are from 2 to 62. According to the TV channel frequency table from Wikipedia (http://en.wikipedia.org/wiki/North_American_broadcast_television_frequencies), it will be roughly 50-800MHz. <br>
