Collinear Microstrip Patch Antenna
Antenna arrays known as collinear arrays CoA are based on in-phase feeding of radiating elements that lie in the straight line and their radiation is typically broadside perpendicular to the axis of collinear elements
Collinear antenna building
A collinear or co-linear antenna array is an array of dipole antennas mounted in such a manner that every element of each antenna is in an extension, with respect to its long axis
Collinear antenna
This antenna design is better suited for people who don't have the expensive equipment needed for fine-tuning. Just build it to the exact specs, put it into a PVC pipe some call it a radome and it works

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
