End Fed Wire Antenna for 10,15,20 and 40 meter band
A FT140-43 toroid to make myself a homebrew End Fed wire antenna,without the need for a tuner
End Feed Half Wave Antenna
E' un semplice L Tuner che adatta l'impedenza dai 50 ohm del RTX ai canonici 2450 dell' Antenna
End fed 6 - 40 Meter Multiband HF Antenna
End fed HF antenna The end fed feature adds portable convenience, but does present another issue.The problem with an end fed half wave antenna is that the antenna presents high impedance
Endfed multibands with tunner

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
