Yagi 2 elements each on 40, 20, 15, 10
This is the 40 meter linear loading mechanism, which is kind of like a giant one turn loading coil inserted in the element about 8 feet out from the boom reflector shown

Monoband yagi for 80 meters and 40 meters
Loading coils for the 80m elements consist of 13 turns of 18 cm of diametre with a total coil length of 20 cm. The conductor is a copper Cu tube with an outer diameter of 6.5 mm
Minibeam Geometry Basics
There is a natural progression of the geometry of the mini-beams deriving from the basic yagi, which in itself owes a lot to the common dipole
New 17M yagi home brewed
The beam has only one feedpoint with 50 Ohm and has an open-sleeve element for 12 m

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening facto
