I seem to recall a method of transposing twin transmission line conductors for RF at regular interval using square spacers with a hole or notch in each corner. This was done to improve the balance over a long line. I looked through all my antenna books but was unable top find any reference to this technique. I guess this is the same as power line transitions described by VY1JA. Peter, G3LDO >
