Broadband Travelling Wave Dipole
A dipole can be modified by inserting resistive loading networks so as to produce standing waves between the feedpoint and the networks. The authors have, by adjustment of the networks and the dipole sections, developed a travelling wave dipole whose VSWR is less than 2:1 from 3 to 15 MHz and does not exceed 2.6 to 1 from 2.3 to at least 30 MHz

40 Meter lazy h array
The LAZY "H" antenna is a general type of antenna that is in the curtain array family. By placing TWO 1 wavelength dipoles in a plane that is at right angles to the direction of maximum
Antenna fra due carrucole
Fa parte delle antenne povere, ossia delle filari
Antenna Tilted Terminated Folded Dipole, or TTFD
Of all the antennas I have built, my favorite is the Tilted Terminated Folded Dipole, or TTFD for short
