The Linear-Loaded Crappie 40mt rotatable dipole
I decided on building a rotary dipole to put at the top of the tower. When fully cranked up, that would be about 55′ above ground leve

Adding 30 and 40 meters to the 4 Element SteppIR
The first thing I did was to extend the fiberglass tubes to the 213 inch length specified
Antena multibanda G5RV
This is an adaptation of the antenna of reduced size to 80 and 40 meters, whose operation was a success.
Balanced Terminated Folded Dipole
Designed my btfd to operate on a minimum frequency of 1.8 mhz with an intended use spaning from 1.9 to 11.0 mhz

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
