capping the tower

[EricH]

I don't think it would have any effect other than blocking the lights on the top and annoying the field crew who has to retrieve the tube that's now >10' in the air. And keeping a tube out of play.

Is it possible to do? I think so. But I also think that risk/reward just ain't in favor of doing so.

I'd personally (and I'm not a ref) call putting a tube over the tower as intentionally blocking deployment via pole contact, if it made it to the bottom. That's not a light penalty, either.
