Limited Space Antennas The Small Transmitting Loop Antenna
The AEA IsoLoop HF Antenna was an antenna I used off the balcony in a Chicago high-rise
Magnet -loop for 80M - 40M
Detail of coupling loop and experimental capacitor theoretically 128 pF/3.2 kV for 80m, 14 pF/5.6 kV for 40m at 50 W
Magnetic antenna for ULF
All the cores are connected in series with a centre connection after 20 turns, resulting in a rectangular coil of 20 + 20 turns
Magnetic Loop Aerial for 20m

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
