The long-wire dipole antenna is effective for low-frequency systems. Adding LC traps makes a single-band dipole antenna into a multiband unit. The historically significant long-wire dipole antenna may ...

When it comes to actual antennas in the real world, much of our knowledge is empirical. We know very broadly theories that explain how a point charge radiates (Maxwell’s equations), the need for ...

Additionally, matching a large capacitive or inductive ... upper band edge frequencies are converted by the famous 468/f to dipole lengths. QST, Oct 1926, "The Length of the Hertz Antenna" shows in ...

Rather than each of the dipole’s legs being straight ... between them and the radio so the only thing needed to match the antenna to the feed line is a coax-to-banana adapter.

Therefore, polarization matching at the two sites is not critical ... they work equally well for transmitting or receiving. The Dipole Antenna The dipole antenna is a half-wavelength structure ...

such that the antenna comprises one entire wavelength. The main advantage of this arrangement is an improved bandwidth over a standard half-wave dipole. * for 75 ohm cable : Lb = La x 0.8 * for 50 ohm ...

In summary, this White Paper is intended to provide a compendium of well-known and obscure facts about dipole antennas and isotropic sources including effective aperture areas, coupling factors ...
