![]() "Walter Maxwell" wrote You've presented a very interesting way of measuring soil characteristics. When I return to Florida in November I'm going to use your method of measuring the soil underneath the dipole ================================= Walt, would it be possible for somebody to go to B.L & E's original site and measure the soil charateristics which they completely forgot all about. Presumably, they were not aware that the type of soil had any effect on their measurments. At what time of the year did they conduct their famous experiments? Pity we shall have to wait till November for you to re-visit Florida. In view of the high temperature coefficient of soil resistivity and probability on permittivity, don't forget to take a thermometer. What was the soil temperature when you made your HF measurements versus height? Soil temperate discrepancies might be of greater order and swamp the effects of considerable changes in antenna height. But I suggest we are more interested in change of antenna impedance versus height above ground than we are in apparent change in soil characteristics versus frequency. ---- Reg, G4FGQ |
