On using a long wire of about 50' stretched between two poles with the
ends directly north and south, will I get the signal from the sides(W and E) or from the ends? -- |

Frequency the antenna will be used on. The antenna's electrical length, and therefore the pattern changes with frequency. 2. Height above ground. If the antenna is less than 1/2 wavelength at a given frequency, the pattern is pretty much omnidirectional. Dale W4OP |

Dale W4OP Roughly speaking a Fifty Foot {50 Ft.} 'Long Wire' Antenna is a Wave Length at 20 MHz; a Half-Wave Length at 10 MHz; and a Quarter-Wave Length at 5 MHz; plus a odd Quarter-Wave Length at 15 MHz. A Fifty Foot {50 Ft.} 'Long Wire' Antenna functioning as a Half-Wave Length Antenna at 10 MHz; would have to be {in 'theory'} Fifty Foot {50 Ft.} above the Ground to 'be' a Half-Wave Length above the Ground. |
