6m 50MHz Yagi-Uda Antenna Computer Simulation Design
I first saw such kinds of articles on Japanese CQ magazine or Japanese Ham journal No.65 in late 80's. I recognized that there was a trial of let's do the optimization of the antenna by using a computer

40 Meter Rotatable Dipole
It is an excellent all-around 40 meter antenna for those who don't have room for or can't afford a yagi
44/28 MHz Transverter
Sono stati sviluppati i relativi circuiti stampati utilizzando dove è possibile utilizzare componentistica di tipo SMD
6AQ5 CW Transmitter
How's this for no-frills hamming? This cute little 40 meter CW transmitter is nothing more than a 6AQ5 oscillator coupled to the antenna

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
