Incidentally remove the RF in the schack, distorted antenna radiation patterns, reception of ambient electrical noise
Triple ratio balun
The first TRB I built is shown in the photos below. I wound it with four quadrifilar turns and 8 bifilar turns
Tipos de balun y unun
In this blog different types of balun and unun are presented for use in amateur radio frequencies. The emphasis is on the HF band 3-30 MHz
Baluns 1.8 a 30 50 MHz
Building a Balun is a relatively simple job. The transformer uses two ferrite tubes, material 43 or 61, or other material with permeability 125 to 850
