EndFed Antenna, ferrite rod matching unit for 40mt
The antenna consists of 20M or 65.5 Ft of insulated stranded copper wire about 20 AWG or 1mm, if you are using it as a portable antenna
Endfed 6 - 40 Meter multiband Antenna
A trifilar wound, 9:1 UNUN unbalance to unbalance toroid matching transformer that will match the high input impedance of an end fed antenna
End fed half wave antenna EFHWA
A single wire,cut at 1\2 wavelength of the desired frequency,fed at one end,therefore without center isolators and coax cable to make it heavy and bulky
End Fed 1/2 Wave Vertical
This antenna lets you get onto 80m in a horizontal distance of about 12m 40ft when used as an inverted slope with the apex at 8m
End Fed Half Wave Antenna Tuner
The End Fed Half Wave Antenna EFHWA is a popular antenna for portable use There are very few simpler antennas

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
