[Elecraft] Thoughts on feeding a yagi...

[J F]

I'm near the point of installing an old 205BA (5
element 20M yagi) that will be serving a dual purpose.
It will also act as a tophat for a 160/80/40 vertical.
I'd like to ground the driven element. Any thoughts as
to the best way to feed it? 
I've been looking at the old standard gamma match,
omega, hairpin and possibly using a broadband
transformer.
Kinda off topic, but might be of interest...
