The MFJ-1779A half-wavelength, single-band dipole antenna is designed for the 160-meter amateur band, covering frequencies from 1.8 to 2.0 MHz. Constructed from number 14 stranded copper wire, this antenna features a robust centre insulator with a SO-239 coax connector and ceramic insulators at the ends. For optimal performance, users should trim the dipole to the required length, with sufficient wire provided to achieve resonance at the lower end of the band, 1.8 MHz. This antenna can handle full legal limit power, making it a reliable choice for amateur radio operators.

Selecting an appropriate location for the MFJ-1779A is crucial for maximizing its performance. The antenna must be positioned away from obstructions such as buildings, other antennas, and power lines, as these can negatively impact signal quality. The ideal height for a dipole antenna is calculated as one-half wavelength above ground, which can be determined by dividing 468 by the operating frequency in MHz. Variations in ground conditions and nearby structures can affect this optimum height, so careful consideration is necessary.

The dipole can be installed in three configurations: horizontal, inverted “V,” and sloped. The horizontal setup requires two supports spaced approximately 270 feet apart, with additional support at the centre due to the antenna's weight. The inverted “V” configuration, often preferred for its practicality, has the centre insulator elevated, with the ends tied to nearby supports. Lastly, the sloped installation involves elevating one end of the antenna while securing the other at ground level. Regardless of the chosen method, weather-resistant, non-metallic rope for suspension is recommended, allowing for some flexibility to accommodate wind movement.
