A Cost Effective Current-mode 1:1 Balun
A cost effective current-mode 1:1 balun can be constructed from a length of coax and a rod typically used for a broadcast antenna loop-stick, some electrical tape, cable ties, a length of PVC water-pipe and some connectors

Air core and magnetic material experiments to try yourself that demonstrate how various devices actually work

Balun circuito balanceado
The word balun is a contraction of BALanced to UNbalanced transformer, that is, balanced to unbalanced transformer. So the best thing to do is to start by understanding what exactly this concept of balance refers to


Take off angle of horizontal antenna

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

Calculo da Antena Bazooka

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 facto
