4:1 coax balun design Calculator
Here we calculate the half wave length of the matching section of the 4:1 coax balun. Again the equations are taken from the ARRL Antenna Book

Il diametro di ogni singolo conduttore rosso o nero e' di 2 mm plastica compresa, e di 0.75 mm senza isolante plastico
Balun
For some so-called baluns, no throttling action or effect against common-mode currents will be measurable. This means that sheath waves occur and the coaxial cable outer screen acts as an antenna. Domestic interference fields penetrate unhindered over the alleged balun in the receiver

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
