David You didn't mention what kind of openings, if any, already exist in the shed walls.
Two things you can do. 1. Put a gradual twist in the feedline, say one revolution every six feet or so. This evens out the unbalancing due to the nearness of the metal shed. 2. Where you do find an opening to pass the line through, come in directly at right angles to the metal so that the line is only exposed to the edge of the metal as it passes through. I think I read somewhere that the opening should be about three times the width of the feedline, and the feedline should be centered in it. I live in a house with aluminum siding. In the garage, over my station table, I put a 2 inch diameter hole in the wall and covered it with an outdoor plastic entrance box. It has a hole in the bottom for feed lines to come through, while keeping rain out. Absolutely no problems so far, after five years.
