An Inverted L Antenna for Small Gardens
The antenna works very well particularly on 40m ZL, VK, 3B9 and Antarctica worked, on 20m you will need ATU as like the W3DZZ the impedance is high on this band
Attic T2FD SWL antenna
I am also an avid listener of other things on the long, medium and shortwave bands
Antennas for Shortwave
Transmitting antennas are much more critical than receiving antennas, although a receiving antenna can transmit if it is resonant
Antenna T2FD
Vi presento l'antenna T2FD per l’ascolto della banda HF
Coax loop antennas for 160 - 10 meters HF bands
Lacking room for a beverage receiving antenna, we constructed several loop receiving antenna to see if we could find a suitable low /lower noise receiving 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
