wrote: A coax feedline that does not project on a radial normal to the dipole feedpoint will have current induced on its outer conductor by coupling to the dipole -- whether or not a balun is used. Hi OM, This is arguable at best, and suitable newsgroup fodder for endless speculation on the contributions of superposition and the combination of direct and induced currents. The classic study of Engineering reveals one principal: The well defined problem contains its own solution. The omission of the BalUn/Choke is not revealed as a solution to your complaint above. It has already been disclosed by others on how the further application of choking can resolve this crafted failure. Their discussion and my own comprise a general solution that responds to the necessary correlative: What is the degree of coupling? 73's Richard Clark, KB7QHC |
