Start with the operating decision: Plan CHA OCF40 as a complete unequal-leg dipole: 44 feet one side, 22 feet the other, with the feed assembly supported independently and ends kept safely clear.
How the system behaves
Use horizontal geometry when three suitable supports and regional/NVIS-oriented behavior are useful, or the guide-defined inverted-V when one center support better fits the site.
The boundary that prevents mistakes
Survey supports, end fall lines, public access, metal, foliage, feed route, wind, and recovery before raising it; then measure in final geometry.
Use this field sequence
Define the exact configuration and intended path, inspect the complete installation, begin measurements at low power, record the result, and change one variable at a time.
Source boundary
CHA OCF40 User Guide 250513. Use the exact current configuration, components, feed, support, geometry, power, and safety limits; mechanical fit does not establish compatibility.
