I suppose I could take my antenna and hook it up to a suitably beefy PA and do a (potentially destructive) test.
I think Tom's advice to just hook up a SWR meter and turn down the power if it looks like it's shorting might be the optimum strategy. The amp I'm thinking about in this application is the SGC-500, which is moderately kill proof, so if it arcs, raising the VSWR, the amp will shut down, and if the antenna melts, it's an excuse to buy a new antenna without agonizing about replacing a perfectly good one.
However, the theoretical discussion and measurements are interesting. Tom's done a fine job addressing some of those oh-so-hard-to-quantify effects in a mobile installation.
