The MFJ-1742 is center fed wire antenna that, when properly erected and fed
with balanced feedline, will give up to three decibels (dB) power gain on the 20-Meter amateur band, along with directivity broadside to the antenna. In addition, with a proper antenna tuner it will also give good results on all amateur
bands from 5 to 50 MHz. It also will work acceptably well on the 3.5 MHz band, although it is somewhat shorter than a half wavelength. This antenna will handle 1500 watts of RF power (with a suitable antenna tuner). Its total length is
approximately 84 feet.
