4 element 14 mhz yagi for 7 MHz
This article is about how to turn a CueDee 4-element monobander for 14 MHz into an efficient duo band for 7 and 14 MHz with some ingenious handles.
2 elementi Yagi per la banda 40
Mi son deciso di scrivere delle note tecniche e costruttive della 2 elementi Yagi per la banda 40 metri home made OB2-40
Linear Loaded 40m Dipole
Here is my dipole for 40m band. It is a simple linear loaded dipole feeded with 450-Ohm openwire feedline
40 meter Phased Array
Coaxial delay lines in his two-element phased array, and some users still use delay lines with good results

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
