End Fed Half Wave Antenna Coupler


A dipole can be fed anywhere along its length. A centre feed gives around 70 ohm. A Windom type off centre fed dipole fed 38% along its length provides around a 200 ohm feed. The feed impedance at the very end of a half wave is thousands of ohms, usually somewhere between 2000 ohm to 5000 ohm

This type of antenna has same performance as a dipole, but requires only one single mounting point, which makes this concept ideal for portabel stations. Actual bandwith is more than 2 Mhz with VSWR better than 1:1,7

E' consigliato l'uso dei toroidi in polvere di ferro anziche' in ferrite, almeno fino a circa 200-300 watts

Ho costruito questa simpatica antenna dopo aver trovato un piccolo toroide cheassomiglia parecchio al T80
