Noise reduction on 40m
Radiation from power lines, data lines and so on in the antenna, I tried to cut into this noise and for this I inserted two common mode inductors in the power line

Antenna for 40m
The installation of my half-wave antenna for the 40m band. The tuning system is installed at the top of the attic
Capacitive Antennas 7.050 - 3.550 MHz
The capacitive antenna is a very space-saving antenna with good receivings caracteristics for the interior also for sending with 100 Watts
Dipolo para 40 80 metros
This dipole antenna for the 40 and 80 meter bands has good performance and is simple to build
Dipolo rotativo para hf
When it comes to dipoles, we wonder how efficient

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
