An antenna has no power in it.  It is a "passive" device.  The effectiveness of the antena depends upon it's phsyical characteristics and the first electronic amplifier it is connected to.\n\nAn antenna has a specific frequency that it is most effective in capturing.  That length is usually a multiple of the wavelenth of the target frequency.  Typically an antenna that is equal to 1 wavelength is the most effective.  But this is not practical at lower frequencies where the wavelength is very long.\n\nSo the coupling between the antenna and the first electronic amplifier is critical.  The technology is well established and therefore, you can purchase good antennas.  What is more important however is the physical location. Radio signals are interrupted or interferred with by buildings and landscape.  So having an antenna that is unobstructed is the best way to improve reception.  However you have to weigh the location against the distance to the radio or tv or other device, as this will cause signal loss over longer distances.

Your best bet is to contact a company that specializes in this sort of thing. I've got a number of websites below that you could start with which would explain and provide links to helpful information.\n\nThere is software, but hardware is also needed. It is available in the USA, but I can't speak for the rest of the world.

Try, Edmond scientific co,(catalog avail. on the www)\nAlso, they have been found for sale on e-bay.\nOne could also find the nearest Cub Scout leader, and ask for one of thier catalogs.(ez build,simple)\nThere are books,such as "The Ameteur Radio Handbook",\nand more at the local library. \nDuring World war two, Soldiers built them using a "Gillette Blue Blade" double edged razor blade as the diode. I have used this as an example in my classes for years, and while not the easiest to tune, they do work, and they are cheap.

I think Radio Shack has a kit that you make a simple radio i think  it's called a crystal radio. EAsy to build and good project.

That is commonly called "High Band VHF" and is licensed under Part 90 of the FCC Rules and Regs (Title 47).  There are pools of frequencies there for public safety, industrial/business, etc.
