  CIMG1928.JPG - First attempt of the phase controller. I designed the board from a schematic in 'Low-Band DXing' 4th ed. I had design concerns about the SWR at the antenna ports that unfortunately turned out to be valid. Front 3.4:1, Rear 4.2:1, Right 3.7:1, Left 3.6:1. The pot will balance the amplitude, but the reflections will corrupt the phase delays.
