One does not want to create an impedance bump. Ed Laport shows how to
make right-angle turns. See page 396 of "Radio Antenna Engineering". It
works fine with 100 KW.
Can you describe that, please?
Parallel-wire feedline is used with success in 432MHz moonbounce which
are very sensitive to small losses. I don't have any information on
sharp bends, but T-joints and curved bends with say a foot radius cause
no noticeable problems.
