Antenna 23cm 1.2 GHz Links →
Antenna Drawing 23 cm
Si puo' realizzare in due orette, chi ha un po' esperienza
23cm Band Repeater Coaxial Collinear
The following pictures show the stages of cable preparation.Elements were cut 2% less than the published length to force downwards beam tilting
23cm 1296 MHz Bi-Quad Antenna
the bi-quad is also known as a double-quad antenna quad the bi-quad gain is around 9 db
Antenne rideau 23cm
Antenne rideau 23cm 1230 1300 MHz
ATV 23cm low cost
Atv 23cm low cost for sat recevier

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
