On 2.5 MHz they run 2500W output to a quasi vertical dipole. Here is their description: "Each antenna is mounted on a tower that is approximately one half-wavelength tall. The tallest tower, for 2.5 MHz, is about 60 m tall. The top half of each antenna is a quarter-wavelength radiating element. The bottom half of each antenna consists of 9 quarter-wavelength wires that connect to the center of the tower and slope downwards to the ground at a 45 degree angle. This sloping skirt functions as the lower half of the radiating system and also guys the antenna." http://www.bldrdoc.gov/timefreq/stations/wwv.html This should be equivalent or a bit weaker than ERP from the big guns in Colorado running 1.5 kW to gain antennas (KV0Q & AA0RS use 4-squares and W0YG uses a 3 el parasitic). Does anyone have information on the power, antenna and location of the 1851 digi signal from Europe? 73, Bill W4ZV _______________________________________________ Topband mailing list Topband@contesting.com http://lists.contesting.com/mailman/listinfo/topband |
