Construction de Baluns
The transformer uses two ferrite tubes, material "43", "77" or "61", or other material with a permeability of between - 125 and - 2000. The volume of ferrite to use will depend on the power to be passed to the antenna to supply

Toroid & balun Links →
Balun for S-match
In the design of one of my ATU's, the balun using T200A-2 toroid is mounted between two PCB disks and located in between the 50 uH roller-inductor and the 12 - 1200 pF vacuum capacitor
Balun per antenna longwire
Questo UN-UN puo' essere impiegato in abbinamento a diversi tipi di antenne,sia per SWL che per ricetrasmissioni sulle bande Radioamatoriali
Balun per vertical antenna
Si montera' allora il balun sul palo immediatamente sotto la grossa antenna e si fara' salire il breve tratto bifilare che collega l'uscita del simmetrizzatore fino allo stilo centrale ed ai radiali
Balun 4:1 - 1:1
A balun is a MUST for dipoles or similar antennas when they are feed with coaxial cables
Balun Theory
Voltage-type baluns produce equal and opposite voltages at the balun's balanced port. Since low impedance antennas are current fed, a balun that produces equal and opposite currents at its output over a wide range of load impedances is desirable
