wrote: what purpose does the REFLECTOR server during RECEIVE??? Hi Ken, Antennas work the same in both directions, so to speak. The reflector and directors offer the same benefits to both receive and transmit. In a sense they distort the medium around them to present variations in phase such that they add/subtract in a convergence with the "driven" element. They are the optical equivalent of lens elements in a complex lens which aid in correcting aberrations and enhancing/increasing magnification. In isolation, the reflector for a receiver acts as a shield blocking signals arriving from behind the reflector. The success of that blocking action is not complete, but through spacing with the driven element can produce a range of responses which are offset by other considerations (like matching impedance) varying along with those changes. 73's Richard Clark, KB7QHC |
