Please can someone help me with the maths? I've been trying to work out my effective loop area and I cannot get sensible answers. These are the measured or estimated numbers I have: Voltage across "loop" = 24.48V rms - measured Current flowing in "loop" = 0.15A - measured ERP (from far field levels) = 50-100uW (may be less) based on -18dB S/N with M0BMU From these figures I should be able to work out the loop area, but either my calculations are wrong or the figure is correct and the effective loop area is very very small.
