Vertical resonant around 3.5 MHz
The combination of wire is resonant around 3.5 MHz. With a 30 uH inductor, the resonance becomes about 1.83 MHz. A series 68-ohm resistor and 16 25 foot radials brings the feed point impedance

Antenna 80 meter Links →
4 square 3650
Numerous tests and comparisons have shown that the antenna, despite its simplicity, works very well. Local measurements with stations from Rzeszów (6km) showed that F / B is above 20dB
80 and 160 mt-80ft for 80mt or 17 ft for 160mt
This is a vertically and horizontally polarized antenna the Linear loaded 1/4 wave length vertical radiator introduces very little loss
80 m 3/4 wave LLV
This is a vertically polarized Phased array. The left Vertical wire is 180 degrees out of phase with the middle and right Vertical wire. At 1/10 wavelength spacing from the right Vertical wire to the left Vertical wire it is producing a End-Fire Bidirectional Pattern,that developes a Gain of 5.9-DBi
