Default GP -> yagi driven element?

Having failed with yagi recipes, too fancy for rudimentary non meter
owner me, I shall now restore my GP antenna, the one with three spikes
at bottom, and six spikes at its waist.

But why not place it in front of, not atop the 2 inch diameter iron
pipe mast where it sat, and in front of them place a 3rd pole? Voila,
a 3 element yagi to boost 145 MHz transmission to the big city 15 km
away perhaps.

Wait, the GP is much longer than any yagi recipe's driven element for
2 meters. Well, so is the mast much longer than any recipe's
reflector...

And all yagi recipes have elements grounded at the middle, if at all,
whereas my reflector and director would be grounded at their bottoms,
unless I place an extra wire...
