Unguyed angle poles must be set how much deeper?

When a pole is unguyed, there are no supporting wires to resist lateral forces, so its stability relies on how deeply it’s buried. Increasing embedment depth adds resistance to tipping by enlarging the base and improving soil grip, which compensates for the absence of guy wires. The standard practice is to bury the unguyed angle pole about one foot deeper than a comparable guyed installation, providing the necessary stability without excessive digging. That’s why setting it even with the ground or only 6 inches deeper would not provide enough resistance to lateral loads, and going two feet deeper is unnecessarily aggressive for typical installations.
