Let's consider a situation where we can have complete Roy, the type of probe I was considering does take up space, and I understand your point that therein lies a possible / likely explanation for its behaviour. I was thinking along the lines of the superposition occuring within the directional antenna where segment currents would each be dependent on the field from each of the sources (and to some extent field from other segments of itself), and the antenna was where the superposition mainly occurred. But you are correct that the antenna is of non zero size, and the segments that I refer to are not all located at a point where the field strength from each source is equal and opposite. Hi Owen, Why would you think that superposition fails for this? 73's Richard Clark, KB7QHC |
