Balun 1:6-Balun for dickerdipol
First SWR measurements of the completed 1: 6 balun antenna surprisingly showed a SWR of 2 on all bands; only at 80 m was the SWR = 6

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

Noise suppression with X-phase II This device similar devices are known as QRM eliminators or noise killers, makes it possible
The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
