The Dipole Antenna
The basic dipole antenna is of the simplest design, yet most used antenna in the world. The dipole claims a gain of 2.14dbi over isotropic source. The center conductor goes to one leg of the dipole and the outer conductor (braided wire) goes to the other. The dipole antenna impedance ranges from 36 ohms to 72 ohms depending upon the transmission line used, with 52 ohms as the norm. Seperation of the center and outer conductor where the coax or other feedline connect should not extend beyond 1" inch. Always mount the dipole at least it's total length, or greater height above the ground or building for best results.
Below you can use the handy online dipole calculator. Just input the frequency in Megaherts and the results will be produced in Feet and Inches.
