Which is more practical?
Driven element with two directors or reflector, driven element,
director.

IMHO, it depends on what you want the Reflector modifies the dipole
pattern to a given direction. A dipole-director favors a direction but
still has more gain on the side with the director.

Neither one is worth building at 2 meters. A 5 element beam with a
reflector, driven element. and 3 directors could be built on a 4 - 5 foot
boom.

Tam's totaly correct in that. I tried it, only to find that a three
elemnt yagi performs a whole lot less than a silly J-Pole does on 2
meters. That, and your modulation drops out the bottom for some reason
too. 5 elements or more. Fewer elements is just a wast of your time,
effort, and money.
Also, a cheap TeeVee rotor will work very well on such a small yagi
like that!

There was something wrong with that yagi then... Seriously..

A 3 el NBS yagi gives appx 9.4 dbi gain. How is that a waste of time
effort or money? The difference between a good 3 el, and a good 5 el
are not all that large. I have a 3 el yagi for FM mounted vertical. I
hear
stuff on that thing that doesn't exist on a vertical.
This is not to say more elements are not worth the trouble. They
usually
are. But if you have a 3 el that gets smoked by a lousy J-pole,
Houston , we have a problem.
