Regarding part 220b I also had big troubles to give it a regular shape. I don't know why UHU02 choose to give it that strange angle. Perhaps to give the tip a conic edge? Anyway I preferred to redraw it as a simple cross and override the problem (the custom part it's included in my "detail kit"...)
Another thing I noticed only when the antenna build was over (I'm sorry perhaps I should have warned you before...) is that, according to the
photos of the real LEM, the 4 legs of the above mentioned part should be mounted at a different angle (if you look from the front it should appear as a "X" and not as a "+"). But this is not a major issue anyway. I, for sure, didn't think about re-doing it not even for a second! ;-)
