2 or 3 elements yagi 27 mhz
Above is a simple drawing of a 3 elements yagi
3 element yagi for 11meter, I1WQR
Hairpin Matching System antenna convenient way to match the feedpoint impedance of a Yagi antenna with coaxial cable
A simple dipole antenna calculator
A simple Dipole Antenna,the Wire Size can range from 16 AWG to 12 AWG. The larger the wire, the wider the bandwidth

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
