A Deep Dive into End-Fed Half-Wave Antennas (Original)
WebMar 26, 2024 · As you can see I fit a full sized 80m EFHW (End Fed half wave) antenna measured at 130ft. with the general thinking of getting as much sloped at a straight angle. (18ga. Antenna wire in red. Balun and counterpoise in green. Wire does hit and lay on edge of garage roof before laying on house pitched roof.) WebIt must be pointed out that a 1:1 balun should never be used on the second harmonic of a half-wave center-fed dipole fed with coax (like an 80 meter dipole being used on 40 meters). The impedance can be as great as … Half-wave dipoles used on anything other than their fundamental frequency of operation, or any odd multiple of this, will work, but you will need to use an ATU. A dipole used like this is unlikely to be very efficient and this type of operation should be avoided. See more A dipole is quite easy to construct. The length of a half-wave dipole might be thought to be the same as a half-wavelength of the signal in free space, but this is not quite the case. A number of effects, including the … See more It is easy to construct a dipole. Basically it is simply a half-wave length of wire cut in the middle. Typically it may be set up something like Fig 3. While this may be the ‘standard’ type of … See more The maximum radiation from a dipole takes place in the centre. Accordingly, this is the most important area of the antenna to keep as high as … See more bowling league record sheets
