40m Moxon yagi Antennna
The input impedance of our antenna is 50 ohms. The 1: 1 balun with RG213 cable can be made by wrapping the air intermittently with a diameter of 15 cm and 5-6 turns
Antenna for 7 MHz
I started up the Moxon Rectangle Generator and calculated the dimension for the antenna. Then I cut the wire according to the result from the generator and made some supports for the corners and for the feeding point by plexiglass
2M Moxon 2 Element
his 2 meter antenna has 2 characteristics that make it a very favorable antenna to have.The boom length is a very short 40 inches. The 4NEC2 forward gain is reported to be 15 dbi

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
