Why not take a look at the Carolina Windom from Radio Works. It might meet
your requirements.

There won't be much practical difference in radiation from the antenna
itself among the choices. But it's much more difficult to suppress
feedline radiation when the sides have different lengths. Since the
feedline is likely to be in close proximity to house wiring and
appliances, it's probably a good idea to keep feedline radiation to a
minimum. This means using a current balun at the feedpoint, and possibly
another a quarter wavelength or so farther down the feedline. People
using off-center fed dipoles have reported difficulty in suppressing
feedline radiation even with fairly decent baluns, but it should be
possible. Of course, if the asymmetry isn't great, there shouldn't be
much of a problem. The advantage to making the overall length closer to
resonance is a higher feedpoint impedance (which you might be able to
get close enough to 50 ohms to obviate matching) and a bit greater
bandwidth. The trade between this and the potential difficulty in
suppressing feedline radiation is up to you to make.

What I'd probably do is make the dipole symmetrical, match it at the
feedpoint with lumped components, and feed it with coax via a current
balun at the feedpoint. But that's only one of a number of possible, and
about equally workable, solutions.

I'm considering installing an inverted V 40 meter dipole under the eaves
of my house. There is room for a longer arm on one side than the other.

1) Would I be better off making each arm as long as possible and adding
whatever matching circuit is required?

2) Should I make both sides equal to the shorter arm even if this makes
the antenna too short to self resonate?

3) Should I make both sides equal in case there is sufficient length to
allow the antenna to self resonate.

Sorry for the complexity of the question.

Thanks for any help.
