The ATL-3 Loop Antenna
Tuned winding antennas always have a potential 6dB greater signal sensitivity, and provide a better signal to noise ratio than equally sized broadband designs
The magnetic loop
A 10 ft length of 5/16in copper tube gives a 39in diameter loop
Traveling Loop magnetic
The antenna is made with coaxial cable shorting the inner conductor to the braid
Variation on the Shielded-Loop AM Antenna
A common hula hoop is a readily available item that can be used to house a home-made shielded-loop AM antenna

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
