USB/Serial SWR Meter
This project is mainly about software. For computing hardware, I will start with the Arduino UNO R3, and much of the work will be done in its firmware
Tuning Your Antenna
This handy device can give you a lot of information about an antenna. It can tell you if it's too long or too short. It can tell you an antenna's resonant frequency
The Resistive SWR Bridge
The resistive SWR bridge is highly recommended for both beginners and experienced constructors

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
