RADIO WORKS - 80 METERS BIG-SIG LOOP - GIANT MONOBAND LOOP - PERIMETER LENGHT = 1.5 WAVELENGHT
The secret of this monoband loop antenna lies in its total perimeter length, equal to 1.5 wavelengths.
Its gain is close to that of the famous bi-square, despite being much more compact than that one.
It can be mounted as shown in the figure, with the apex at the bottom, or on the contrary, with the apex at the top, or in other configurations such as the rectangular or the square shape.
Thanks to its large capture surface, low reception noise, excellent low angle radiation pattern with good signal gain, it offers the possibility of connecting far away stations much more easily, which is often unthinkable with small antennas.
Thanks to the special dedicated impedance transformer located at the feed point, it is possible to directly use 50 OHM cable without a tuner at the resonance point.
MAX. APPLICABLE POWER: about 1500 W output
