I don't completely understand what you're saying, here. (The statement "the field actually increases but is still non radiating" is probably wrong.) There is a gravitomagnetic effect caused by special relativity, but it's pretty subtle because, unlike electromagnetic field, the gravitational field has no dipole moment.
All orbiting charge does not radiate, for example the electron orbiting the atom. What causes the earth to radiate or not radiate when it orbits the sun?
Electrons don't always radiate when they orbit around the atom because they're hard up against the Heisenberg Uncertainty Principle; there's no lower energy state available. There is no such consideration when it comes to the Earth in its orbit. It will radiate gravitational waves continuously.
What gives the phase quadrature components so it doesn't radiate? Or what are the in phase components to give the radiation? Gravity then must have a wavelength and phase in order to radiate.
Again, I don't really understand what you're saying. "Gravity" doesn't have a wavelength, as it's a field. (Geek alert: if gravity can be described by a quantum field theory, then the field could be decomposed into an infinite superposition of quantized virtual gravitational waves, just as the EM field can be described as an infinite series of virtual photons. But that doesn't mean that the field would in any sense have a wavelength.) Gravitational waves--that is, changes in the gravitational field--would have definite wavelengths. It's a whole new spectrum.
The difficulty in detecting gravitational waves is primarily due to their long wavelengths. For example, the gravitational waves radiated by the Earth have a wavelength of exactly one lightyear, because it takes the Earth exactly one year to complete one cycle. Measuring such a wave would require an apparatus of about that scale. LIGO is designed to measure much shorter wavelengths, but the processes that generate gravitational waves with such a short wavelength are few and rare.
