I think you solved your own problem with the antenna situation, but for what it's worth, I asked a similar question to this list last year. Your solution is exactly what I ended up doing: Extend it through the bulkhead, then put a straw around it. That has worked fine for me. Either way, don't bend it too much.
I have used Q2G2 igniters for charges and they worked great. Just be careful with them because they're very thin, solid-core wire, so they don't take well to lots of flexing.
