Anyone ever get around the VHF FM vertical yagi feedline routing
problem by voltage feeding the bottom of the driven element with a stub
like a J-pole? A quick EZNEC run seems to indicate that it's not a bad
idea.

So it seems like it might work OK... but I wonder if anyone has
actually done it. Would you expect a coaxial stub to work better than
a parallel wire stub in terms of preserving the pattern of the yagi?

Any commercial products doing this?

There's an example of a 4ele 2m J-fed yagi in the MMANA files. It has a
gain of 7dBd. Free space pattern is skewed up by 1 degree, but a real
ground will do that anyway.

I don't know of any commercial versions.
