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 Half Wave Antenna Tuner
The End Fed Half Wave Antenna EFHWA is a popular antenna for portable use There are very few simpler antennas
End Fed Halfwave Antenna And Matching Unit
My favorite antenna for portable use is the end fed halfwave or EFHWA. I have documented some of the earlier ones I built in my pedestrian mobile pages
