Symetriseurs, adaptateurs d'impedance BALUNS
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

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
Build a Three-Way Antenna Switch and Displa To use a wireless relay to select one of two high current capacity power relays
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening factor
