Can someone give the correct length of antenna wire need for each frequency?

some repost this info?Thanks in advance...
The length of wire will change depending on the antenna type so you
will need to be more specific. If you meant to ask about a single wire
antenna then the answer is a 1/4 wavelength for the frequency of
interest.
The single wire antenna needs a RF ground to be effective so use a
ground rod or lay another wire on the ground under the single wire
antenna. You can improve the the wire performance with an UNUN coax
cable to wire impedance adapter at the RF ground rod.
Usually single wire antennas are not cut to a specific length and as
such are loosely defined as random wire antennas. Use a wire from 75 to
300 foot long for a table-top type radio and no more than 75 feet for a
portable radio or you may over load it.
