Hi,

Please tell us how long?? With coils atleast it not possible I think.

Thankyou.

That will be difficult becouse of the tuning. You can make your own coils. Its not that hard. I'm sure their will be schematics and or tutorials on the net on how to make your own coil

Cheers!

There is also the problem with the radio laws. They generally limit the output power so that these devices have very short range. If you get a license for it (which may not be possible in your country), you will have to meet some stringent performance requirements.
