Project Building a SWR for measuring 23 cm
Here I will show how to use inexpensive components craft box, flea market, etc. to make a device that is suitable for our purpose
Ricetrasmettitore 1 . 3 GHz
Ricetrasmettitore a larga banda per collegamenti packet sulla gamma 23 cm
Simple band-pass filter for 23cm
The design seems to work well; I tried a prototype with adjustable input taps, and found that the input and output tap positions on the lines were not too important

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
