Making the LFA Loop
To build an LFA but the prospect of making a loop is a little challenging
Multi-loop Rectangles and Compact Arrays
Is composed of four rectangles. But, before studying this antenna and its use as an array component
Octoloop antenna is a shielded multiturn loop
The octoloop is easy to make You need some 3/4 in hard copper pipe, eight 45 deg elbows, and two male threaded adapters
Portable Magnetic Loop Antenna 20, 30
Described here is a simple multi-band magnetic loop antenna designed for 20, 30 and 40 metres
Programma di calcolo del condensatore
The diagram shows a capacitor with three 4-square-inch plates, separated by 0.25 inches of air. Its calculated capacitance is 7.18 picofarads

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
