A Neat Invisible Indoor Aerial

Introduction: A Neat Invisible Indoor Aerial

About: I love doing practical things about science, but, sadly, it is not quite what you usually learn at school, so for the last 8 years of my life I remained the only crazy kid who has a closet full of metal junk...

I wanted to build an aerial for a very long time, but a roof or outdoor one doesn't suit me, as there are no trees near my window and it is impossible to climb on the roof, so I had to make do with an indoor one. I made some research into indoor aerials, but the only type I found in a bunch of old books I own is a net of antenna wire on a rather large window frame. I think it is ugly and I don't have large windows either, so this is my solution. It is neat, almost invisible and doesn't spoil the interior with millions of nails under the ceiling and hanging wire, while it is able to provide hearable  signal from a crystal set.
Well, the picture isn't very useful, but I was supposed to make an INVISIBLE aerial, so how can I make a proper picture of it?

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Instruments

As I don't want to spoil any walls by excessive hammering, we won't need many instruments, so it is highly unlikely that you don't own any of these.

Step 2: Start Working

Most rooms, at least all bedrooms and living room in my house - everywhere, except the kitchen, and you are unlikely to build an aerial in the kitchen, have that sort of foam molding glued between the walls and the ceiling. Start with leaving a length of wire to descend from the ceiling to your table ( or anywhere you want your aerial to end), take a chair ( or anything to help you reach the ceiling, I used a stool and a crate on it, but I'm not very tall)and begin working by making a slit between your wall and the molding ( the sort of foam it is made of is easy to crush) and pushing wire in it with the same screwdriver. My photo is a bit blurry, but I was standing to a wobbly crate on a wobbly stool with a screwdriver in one hand and a camera in the other, but you can see the principle from it.

Step 3: Continue...

Walk around the room pushing the wire in the slit (it is quite a fast process, but avoid loops).
The second picture is my finished (invisible) product.

Step 4: Earth

If you are interested in my earth, here is the picture ( it explains everything)

Step 5: Finished

So this is the final view. See, no one could've guessed the is an aerial in this room ( well, maybe if you see what's lying around on the table). 
This is my first Instructable and I'm not very good with either computers or punctuation, so please excuse my clumsy style.

    Simple and great for apartments and such. A BETTER antennae is outdoors. A simple and great one can be made from farm items. Electric fence wiring (rust-resistant) and fence insulators placed at corners and about every 10" under the eves with an insulated lead going inside to the "input" on the backside of a radio. That will pull in anything available and works fine for any radio/shortwave/Cb reciever. Much will depend on the reciever. Years ago - my 'Channel Master' AM/shortwave/CB reciever could "hear BBC in England - Japan - Most shortwave 'traffic', and any 'local' CB calls. The 'net or library is a good source of specific wavelength antennae, etc.

    Good instructable. Did you intend this antenna for AM? I assume so, but it would be handy to add that to the instructable.
