A perfectly matched antnna only reradiates 50% of the energy it receives. Best regards, Richard Harrison, KB5WZI Richard, Some time ago I stated that a yagi antenna operated under a mathematical binomial function. This was termed as junk science in this group which raises the question again as where does the energy that is not reradiated go ? " A perfectly matched antenna only reradiates 50 % of the energy that it receives" This also suggests that an array without parasitics required for reradiation is a lot more efficient than an antenna with parasitics. Seems like this group is going around in circles unless this 50% finds a way to radiate in some alternative way ! Is the 'perfectly matched' statement of any importance that demands it's inclusion with respect to re-radiation efficiency of an antenna? Regards Art |
