Step 4: Make/attach antenna reflector

Take your piece of cardboard (approximately 2'X 3' in size) and cover one side in aluminum foil or some other metallic covering  A heavy coating of spray mount adhesive will hold the aluminum foil in place on the cardboard.

Using some of the same screws you used to to attach the wire lacing/"Vs" to the frontside of the board, attach the cardboard reflector to the backside of the board, with the aluminum foil facing towards the antenna.
<p>First prototype. Yes, ugly as hell. We named it &quot;el engendro&quot;. </p><p>On the other hand: it works great. :)</p>
<p>Hey weblar; we are stuck in the middle; completed the construction but it ain't even catching a glitch; please help.</p>
<p>i want to know about frequency range of this antenna and it will be work in india ?</p>
<p>I can't understand how to connect to antenna to TV using Coaxial cable. Can i do it without a balun and 2-set splitter?</p>
<p>The short response to your question is &quot;no&quot; - you need a balun to convert the signal gathered by the antenna to a format that can be carried by the coaxial cable and used by your television. If you construct this antenna with 2 antennae, front and back, you can join the 2 antennae into one signal with the 2-way splitter.</p>
<p>I am using a single antenna but it is not picking any channels; please help.</p>
<p>Can i use iron wire?</p>
You can use any kind of wire that conducts electricity, including copper, aluminum, galvanized steel or iron wire.
<p>it is good </p>
<p>Made one a few years ago, the thing worked great. I ended up leaving it at my old place when I moved and am looking to build another one. </p>

<p>Interesting article - thank you for sharing and we'll give it a go. Does this have to be galvanised or would some of these other types do:</p><p>http://www.caparofairbrightwire.com/bale-wire-range.aspx</p>
Other types of wire will also work well for construction of the antenna, PROVIDED the wire is not insulated.
<p>Nice additions to the first version of this I came across, and which you mentioned on page 1.<br><br>However, I do have one point to perhaps reduce the work load. You stated that if you want to receive signals from more than one direction one could build a second antenna and then add more aluminum to the back of the first reflector.<br><br>Adding more aluminum is not necessary since the first coating of aluminum will reflect to the second antenna just as well as more aluminum will. The RF will have no difficulty going through a thin piece of wood or cardboard to reflect off the aluminum on the other side.<br><br>Next, I've done experiments that show that the length of each element doesn't change the overall characteristics of the antenna very much so as long as they are cut to the same length and the lengths are close to the design length all will be well. I haven't yet tested two or four different lengths to see what difference, if any, that makes. Humm, in some ways that's what a log periodic is all designed around, but not for the same reasons.<br><br>On the other hand if you don't need the reflector, I don't think it will add much but I haven't tested to see if I'm right, yet, and if you have stations in more than one direction I'd suggest making my 3D version of this antenna.<br><br>I designed what my wife calls the porcupine antenna which uses no reflectors and two of this type of antenna at 90 degrees from each other so that stations from any direction are received. We use two of these for TVs in two different locations in our house and we get stations from North East to South East, to South West and to West. The one TV station to our North is too far away for this antenna and is just another NBC station anyway.<br><br>You can see this antenna on my web site at: <br>http://cs.yrex.com/ke3fl/Articles/Antennas/BuildingThePorcupine.htm<br><br>Or, if you're in the heart of the city you can simply use only one section of the porcupine antenna, just a simple 3D version of the ol' bow tie antenna. I designed that antenna back in 2002 and the article was published in Popular Communications, January 2003, p 6-10 , &quot;Phil's Easy Way To Improve Your UHF TV Reception&quot;<br><br>Oh, one last note here. This antenna is a UHF antenna and while it will receive VHF stations it doesn't do it well so if you have VHF stations at the same or further distance than your UHF stations you may need to add a longer section, a VHF dipole, to the center of this antenna to improve the VHF reception. I've seen articles about this, but again I have not yet tested the idea.<br><br>To see my TV antenna tests you can go to my articles on solidsignal.com. I've tested, &quot;Bow Tie Element Length Evaluation&quot;, &quot;Transformer Tests&quot;, and &quot;Bow Tie Antenna Angle Tests&quot;.

<p>I moved recently and while I previously had a 'profe$$ional' roof mount installation my new place was not going to accommodate such a setup. I cobbled this together last night from some odds and ends then just generally shoved it in to a window. Receiving 19 of a potential 26 channels which I am sure I can improve on with a little tweaking and/or getting this up in to the attic.</p><p>My son was impressed....'hey Dad how did you know how to make that?'..... instructables son, instructables.</p><p>thank you for posting.</p>

I made it with fencing wire and it works GREAT! <br>I get a lot more channels than before, and all crystal clear. <br>I did not add the reflector, and I wrapped the whole thing with electric tape. <br> <br>Thank you so much! <br> <br>: )
I built one out of scraps and all I can say is thank you. It works!
I made one...a smaller version that hangs on an interior wall. Without the backing. Smaller...only 16&quot; long but every single channel still comes in. Pretty cool!!!!
Nicely Done.<br>MacGyver would be proud.
I have built a similar antenna and it works EXTREMELY WELL in the UHF, but not so well (for the sizes of this particular model) in VHF.
<p>Here's my ugly antenna that seems to work better for UHF. Complete instructions and measurements in comments: https://www.facebook.com/photo.php?fbid=10153288059505272&amp;set=a.10150944639615272.470943.683865271&amp;type=1&amp;theater</p>
<p>I meant VHF, of course.</p>
One of the comments I read relating to the original design that I modified for this Instructable was that the lengths of wires for the &quot;Vs&quot; in the original design favored either UHF or VHF (right now, I don't recall which); but the commentator suggested the alternative wire lengths in order to accomodate a broader range of signal. <br> <br>I am able to pick up and watch television stations from Channel 2 (the lowest station I can pick up, and one of the stations further away from me - over 130 miles) to Channel 50 (the highest available station, and again far away - over 150 miles) using the antenna dimensions/wire lengths depicted in this Instructable.
Excellent! I am quite sure the lengths you are using are best for UHF, but then again, you know it works and that's what counts! <br><br>When I built an antenna like yours (almost identical!) it worked very well in the UHF but I could not get any VHF. Then the design I used for a DIY VHF was more like this:<br><br>http://www.qsl.net/sv1bsx/6EL-VHF/6EL_VHF.html<br><br>I built it out of wood and some copper wires and put it in the attic, and worked wonderfully well.<br>
