: .... The two 100 ohm loads in parallel give a 50 ohm load to the 50 ohm coax main feed line. I used a ferrite "balun" where the unbalanced 50 ohm *main feed line* connects to the center conductors that are connected to be a 50 ohm load. . You didn't mention the balun in your fist posting. Without an effective balun, the system would be quite poor. In each pair of antenna side coax lines where the shields are tied together and the inners are used for a 100 ohm connection point, you drive one coax in opposite phase to the other. Your description did not note that there is particular phasing requirement for the coax lines to the antennas, and polarity of connection of the DEs. BTW, you have constructed a type of power divider. There are a lot of different ways to do it. Owen |
