What is the best resonator in Yagi antennas?

As we saw many design for this Yagi feed point.

Q1 . Which one would be the best resonator / driven? Gamma match, T-match, delta match, folded dipole, quad, loop?

My question apply for VHF band. Narrow bandwidth preferred. Design complexity and economical cost are doesn't matter. Highest gain is the main goal.

So far, I've build Super Boomer, Special ZL and T-match. And actually, I don't know which one is better. I only have a home brew RF strength meter here, and it seems they radiate the same strength.

So it's come to my mind that these driven things are big enigma to me.

• Can you make your question more concrete? In particular, specify what you mean by “best”. Highest gain? Loosest tolerance in construction? Easiest to build? – Kevin Reid AG6YO Jun 12 '14 at 20:03
• Widest bandwidth? Lowest windload? Lowest cost? – Phil Frost - W8II Jun 12 '14 at 20:26
• Aha! In this case is performance, it's gain. Anything else doesn't matter. – Bianca Jun 12 '14 at 22:45
• @Bianca Thanks for specifying. Could you edit your question to make this clear? – Kevin Reid AG6YO Jun 13 '14 at 3:03
• @KevinReidAG6YO Thank you. I just edited. – Bianca Jun 13 '14 at 3:31
