Feeding the Antenna
If you're using a nonresonant antenna and matching it with an ATU in the shack you could be amazed by how much power you're wasting. more
G5RV wire antenna 10-40 Meter
The ladder-window line is aprox 450 ohm impedance, you will be using 16.5 ft of this line
Home Brew CW Filter
Newer radios may come equipped with filters for narrowing the audio passband or digital signal processing (DSP) to clean up unwanted noise

This is one of my homebrew qrp projeckt collections. 144 MHZ QRP TX FOX BEACON is very simple but the power out put is around 100mw enough to be made in the FOX HUNTING event

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
