Antenna Windom Multigamma
I vantaggi cche ci offre questo tipo di antenna e' quello di avere una multibanda con un solo dipolo

Antenna windom 40-20-10 metri
Questa windom ha una lunghezza totale di 20,37 metri calcolata su la frquenza di 7,07 Mhz
Antenna windom
Si tratta di un dipolo con alimentazione asimmetrica,in grado di risuonare dai 10 agli 80 m
Carolina windom
Ease in its manufacture which is certainly a multiband antenna too, can radiate at 40.20 and 10 Meter band without ATU with the addition of a 1: 1 balun choke
Variation on the Windom
It's a simple aerial, and a variation on the Windom. It is an asymmetric dipole, the feed point being 1/6 of the way out along the radiator, rather then the 1/3 + 2/3rds arrangement of the typical Windom

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
