In the real world we try to get maximum results with minimum investmennt in effort and materials. An unbalanced 1/4-wave or a balanced 1/2-wave seems appropriate. As far as angles go, polarization is the direction of the electric field, usually horizontal or vertical for mechanical as well as electrical purposes. You can take Kraus to the bank. Check his index for "Mutual Impedance" of paralleled dipoles or echelon antennas. Better yet, you likely have experience with trials of cross-polarization of VHF or UHF antennas. You have seen the havoc cross-polarization causes. Now, is there any angle between fully aligned and completely misaligned where we discover a magic peak? Of course not. Best regards, Richard Harrison, KB5WZI O.K. you WIN Richard. You run so many different routes that I can't keep up with you. You deny the validity of computor programs and Roy sulks because none of his programs have the optimiser feature which is the easiest way of solving the question. You can place the radiator where ever you want to get the results that you would like to see.So you don't trust computor programs, programmers or you just never tried to use them? You can now get back to argueing with Cecil on coil currents which will allow some more disconnecting reading from Terman of yesteryear. There is nothing more to be said regarding the resultant vector of a radiator's active vectors which is the basic issue that I was discussing in the first place. Hopefully you will recover by morning and look on life in a different manner. Art |
