Horizontal Loop Loading Methods
The primary radiating area of a half wave loop is about 1/8th wavelength. We are essentially end loading a 1/8th wave long dipole when we use a 40 meter full wave loop on 80 meters

Vertical Loop for 80-6 Meters
loop antennas have always fasci nated me. From a common sensestandpoint they seem impossible.I mean, how can you have a short circuitat the output of your transceiver
Yet another delta loop antenna
I decided to try a loop antenna and I only had one mounting point on the paneling, so I used tape to make a triangle, but if I used an equilateral triangle as in all of the antenna books, I would have to put a nail in the middle of the paneling
Delta loop rotable for 40 m
the delta loop has an impedance of about 100-120 ohms. a quarter wave of 75 ohm coax is used to transform the impedance down closer to 50 ohms

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
