Antenna delta loop 6 metri 50 MHz
L'impedenza caratteristica della Delta Loop, presenta un valore di circa 125 ohm, mentre il suo guadagno e' di circa 1,4 dBd
Antenna boomless tribanda per i 50/144/440 mhz
Questa realizzazione occupa poco spazio, e' leggera, non necessita del rotore
Chris Gare's 50MHz Power SplittersThe use of power splitters and combiners is widespread in amateur radio but the design of these circuits is often considered to be a 'black art
50 Mhz 2el HB9CV
50 Mhz 2el HB9CV for band 6 meter
COAX antenna projects 2 and 6 meter
Uses formula for calculating the coax lengths 984 x .66/your frequency/4= 1/2 of the driven element, but I did not leave the 20% longer sections as I was not going to use insulators

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
