Coaxial Dipole antenna
A coaxial dipole, it is very different to a conventional dipole; it incorporates a balun and is almost like having two quarter-wave dipoles connected side by side

The G5RV Multiband HF Antenna
The interaction between the radiating section and the feed-stub makes the G5RV easy to match on all-bands from 80 through 10 meters with an ordinary low-cost antenna tuner
The Inverted "L" Antenna
The Inverted "L" is a 1/4-wave Marconi, fed against ground or a counterpoise such as radials
The W3EDP antenna
The W3EDP end fed wire antenna lends itself readily to QRP and portable operation
20 meters Cage Dipole
I badly needed an antenna for 20 meters. It was when the Cage Antenna solution came to my mind

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
