The QST article was no surprise to me. The screwdriver is a base loaded antenna. That makes it so popular (And for good reason) is that you can remote tune it, in fact there are many companies that make automatic tuners for it some of which interface with your radio so that you can do seamless band switching. Just change bands on the radio, push the auto-tune button and... Whirr,Whirr. tuned.

However it is a published fact (Most any antenna book) that base loaded antennas are not as good as center or top loaded antennas

The ones that outperformed the screwdrivers were all center or top loaded.

Now, a fully automatic, trap tuned, all band center or top loaded antenna. for mobile use

I don't know of one
