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? -- We need *more information. 1. 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 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. |
