WebHere is the pattern of a 145-foot high copper wire dipole over medium real earth on EZNEC: dipole gain in dBidipole gain dBi. You can see the gain is 8.5 dBi, and it is just a simple dipole just over 1/2 wave high. Any antenna you model should always be compared to a standard like this! WebAn 80 M half-wave off-center-fed dipole, with a feedpoint at about a 22.5% offset from one end, will give access to all HF bands from 80 meters up to 10 meters.
