<>The answer depends on what you need the antenna for. For instance, a shortwave radio receiver (not transmitter!) can use a length of wire of anywhere from 30' to 50' strung between to insulators with a lead-in wire. I suggest you search (yahoo or google) and specify what you want (eg: "shortwave radio receiver antenna plans").

Technically, any straight piece of wire will act as an antenna. But, antennas are specifically designed for a range of frequencies and can vary from one 'rod' systems like your car antenna, to multi rod systems such as the old roof mounted tv antennas, (logarithmic). Designing an actual antenna is not a simple task and can be quite complicated depending on the frequency range you are trying to 'tune' too.

you really need to be more specific , a basic crystal radio antenna can be 10 or 20 yards of wire strung up, try searching search engines like google

it depends on the what you're doing with it. High frequencies require different lengths and power than low frequencies. You need to be more specific.
