It's probably a stupid question, but I can't help myself.
I made a short jumper with LMR 400 with a PL259 on one end and then seperated the braid
and the center conductor to attach ring connectors to attatch to the antenna. I then covered
both with heat shrink to help keep the weather out.

The question is I left the foil arount the center conductor up to the ring connector. Of course it's
not connected to the center conductor. Will this create a problem?

It took a minute, but I got ya'. No, it should not hurt. Now if you're running full legal limit and tuning out a high VSWR the voltage there may be an issue if the foil edge, which can exceed voltage breakdown easier, is close to the center conductor. Myself, I would separate them a bit more, but that's me, it may be nothing.

If I were making jumpers I would use LMR-400UF I could see a problem with regular LMR-400 with the bending to sharp an angle.
