Hello All, Below is a quote from the Stefan's web page concerning his latest "Dreamers Band" DX contact Congratulations again Stefan. "100m Vertical wire antenna, coil/antenna voltage was abt 15kV rm
Hi Paul, it sounds like your impedance bridge is measuring the absolute impedance (that is Z = (R^2 + X^2)^0.5 where R is the real part, resistance, and X is the imaginary part, reactance). R is prob
Dont forgett here is a small inductance component in a wire antenna as well, this can become insignificant as you move well away from resonance. but the series capacitance I measured at various frequ
I wondered that, but 500pF as measured, if genuine at 10kHz, works out at -j 32000, which is close to the 70k Real term. The series equivalents are therefore 12k - j26.5k - which still doesn't s
Hi Johan, an Impedance bridge measures the reactance and resistance is parallel I believe....doe sthat make a difference to what he is seeing?? Alan G3NYK "Dreamers Band" DX contact Congratulations a
Dear Paul, LF Group, For Stefan's benefit, 1' = 0.3048m, so we are talking about a 52m long wire. I measured my home QTH inv-L antenna (about 55m of wire in total, about 10m height) at 10kHz to have
That sounds about right for a sloping 100m wire.....an oft quoted figure was 5pF pepr metre for the vertical section and 6 pF /m for the horizonatal top-load. Alan G3NYK Addition: When i replace the
