Video Analysis of Half-Wave Dipole Antennas. In this video, we go over the short-dipole antenna, the half-wave dipole antenna and the general dipole antenna. The idea is to give an intuitive overview of the first 3 antennas we've discussed.

Antena End Fed – wielopasmowa antena, która dla wybranych pasm będzie pracować bez konieczności stosowania skrzynki antenowej. Świetna antena do pracy w terenie, podczas aktywacji gmin PGA, parków jak również szczytów górskich w programie SOTA. Lekka antena drutowa zasilana z jednego końca.
Learn about the construction, working, radiation pattern, advantages, disadvantages and applications of half wave dipole antenna. It is a type of antenna with a length equal to half the wavelength at the operating frequency.
Dipoles whose length is approximately half the wavelength of the signal are called half-wave dipoles and are widely used as such or as the basis for derivative antenna designs. These have a radiation resistance which is much greater, closer to the characteristic impedances of available transmission lines , and normally much larger than the ...
A half-wave antenna (referred to as a dipole, Hertz, or doublet) consists of two lengths of wire rod, or tubing, each 1/4 wavelength long at a certain frequency. It is the basic unit from which many complex antennas are constructed.
antenna is based on any number of parameters: specifically, the frequency or band of frequencies, location, directivity, and intended power range. This paper discusses some of the more important aspects of the End Fed Half Wave (EFHW) dipole antenna. The frequency band is HF (40 meters), and the intended power is 100 watts.
waves radiate in expanding concentric circles; radio waves from an antenna radiate in expanding concentric spheres. When one wave follows after another in a long succession of waves (as they normally do), we have what is called a wave train. When a transmitter is sending a signal, its antenna is launching into space a wave train in
