4el @EU for 20m redesigned

I’ve said for a couple of years that we need to redesign the 4el for 20m since the bandwidth is a bit narrow and it differs too much from the other antennas, so the amps gets problems when switching antennas or powersplitting. Now when the neighbour took back the concrete mixer because he needed to mix some concrete for his sister, and I was wondering what to do SM2XJP gave the suggestion to take down the beam. So we did and put it up the next day with another design (OWA) which I had already made, it just needed to be transfered to the correct tapering. The result is great, now the SWR is not over 1.3:1 on the whole band and is a lot more similar to the big stack.
