TAK tenna for 80m
My HF antenna is a TAK-tenna 80m model, which is essentially a spiral dipole

ZMV spiral antennas
An experimental antenna similar to the TAK spiral antenn


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
