40m Moxon Antenna
The input impedance of our antenna is 50 ohms, balun 1: 1. with coaxial RG213 of 15 cm in diameter and 5-6 turns from the winding

40m Moxon yagi Antennna
In this antenna, 4 pieces of 6-7mt of fishing rod were used
10m Aluminium Moxon Construction
Bending the tubes was a challenge, I eventually borrowed a pipe bender for 15mm copper pipe and used this It worked satisfactorily and I used a hand held pipe cutter to cut the tubes
Six Meter Moxon Antenna
One fully portable 6m Moxon beam that breaks down into a bag easy carried off and easy to assemble in about ten minutes
20-meter Vertical Moxon
In the end the antenna ended up resonating closer to the upper edge of the 20m band around 14.275
Moxon for 70cm
The antenna is broadband, has a broad (100 degrees) front lobe, a good front-to-back ratio and a useful amount of forward gain and presents a decent near 50 ohm match at resonance

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
Atu balanced feeder antenna system An ATU has the advantage of bringing the feeder-antenna system to resonance, act as a band pass filter both on receive and transmit and a low SWR
