Introduction: Cheap Wall Antenna.

Picture of Cheap Wall Antenna.

Simple TV antenna kit.  Saw this antenna (lknown as the Walltenna) advertised for about thirty five dollars. We could not see paying that for such a simple design, so we made one ourself.  We was surprised how well it worked even for the crude model we made, excepting maybe one station that I really liked to watch.If it looks ugly, you can always cover it with a picture. Last frame is an antenna that has been around for years.Looks familliar

Finally made a sort of very crude "ClearTV" antenna. Yielded over 50 channels/

Step 1: Needed

Picture of Needed

1 - Dollar Store baking sheet. (They come two for a dollar).
1 - Tv transformer
1 - 16.25 by 12 inch cardboard piece for a backing plate.
Tape or glue

Heavy duty scissors.

Step 2: The Base.

Now you need to cut out the center of the pan so you can make the strips for the antenna.

Step 3: The Pieces

Picture of The Pieces

You will want to score the aluminium and then cut out the pieces as shown in the picture. 
8 - 7 inch long pieces
2 - 2 inch long pieces
2 - 6 inch long pieces
2 - 9 inch long pieces (You will eventually probably shorten them.

Step 4: The Backplate.

Picture of The Backplate.

You will want to cut out a 12 x 16.25 inch backgound to hold the antenna pieces. We used simple cardboard.

Step 5: Laying the Pieces Down.

Picture of Laying the Pieces Down.

The seven inch long antennae with a 3 inch width is pretty much a standard. Used the same dimensions in the first antenna we made. Lots of prior art with this pattern.
Take two of the 7 inch pieces and form am arrow with a 3 inch width at one of the long corners.
Repreat this step at the other three corners with the remaining six 7 inch pieces.

Note: All metal contact points that intersect must not be glued. 

Step 6: Remaining Connectors.

Picture of Remaining Connectors.

Add (attach) the remaing connectors. The 9 inch pieces will connect the arrows. You may have to thrm them a bit.
The six inch pieces go in the center,
The 2 inch pieces will connect the six inch pieces to the 9 inch piecees.
Attach your transformer to the bottom poings on the six inch pieces.

Step 7: Tada!

Picture of Tada!

Hook the antenna to your tv. You will probably want to rescan for the available stations. We still have the old converter box, but rescanning the stations still applies. Happy free tv watching. Success of the antenna will vary depending on the number of stations in your area. We get over 100 digital television stations.

Note: Lot of glare so the pictures did not come out well.  Updated pictures later.

Some of the other antennas we have made.

Everyone if you want more channels check out.

They have 3 variants of 4 bay bow-ties. Remember the longer the whiskers the lower the channel the antenna is tuned. I made the 4 bay 9" whisker 8.5" spacing in foam core. I pick up 69 (real UHF channel 46) from Allentown PA from my office at Villanova University(BTW everyone has left for Huston)! That 36+ miles from inside a stone building.

My main indoor antenna gets me over 120 channels.

Had an old roll of copper tape for Tiffany glass. So I made one on foam cor board with the tap. I had to Scotch tape the cooper down because the adhesive on the copper was so old. I also connected the Balun to the mid points between the bow ties rather than run the lines to the bottom.I then wire tie the coax to the foam core. works great on the wall in my office.

hey, How I can made the same antenna but a little more big, I would like to gain more channeles incresaing the size

Not and engineer, but the lengths are set to get the most stations, in-line amp might be a better choice.
