A Simple 50-ohm Single-Band Balun
The balun herein described is suitable for 50-ohm monoband antennas which can often represent a valid choice

Choke Balun experiment
I was aware from some early experiments on cores FT240-30 windings would have high resistances as well as fairly high inductive reactance
Vari balun Balun 1:1 - 1:4 - 1:9
Baluns BALanced to UNbalanced are still a mystery for hams; the only way to understand this is to learn what it is and how to use it

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
