3 element Yagi antenna 433 MHz
A simple tape measure based 433 MHz 3 element Yagi antenna
Build a lowcost yagi antenna for PMR446
It is a 6 element version where the dipole is left out
Yagi 14 elementi autocostruita per PMR446
Here is my first reliable and still working Yagi antenna for my radios PMR446, 14 elements, 2.5 metres long, gain 13.6 dBd.All elements of this Yagi antenna are made of solid aluminum, only the dipole elements are made of aluminum tube, recycled from clothesline, so that in a moment, with a vise, I pressed the ends where I connected the RG58 cable

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
