Basic Antenna Theory
To reduce the size of the dipole, several options exist:
4
•
•
•
•
•
Replacing some of the wire length with loading coils
Bending the dipole ends back on the dipole
Folding the dipole into a meander pattern
Hairpin or coil loading of the center
Capacitive loading of the dipole ends
