What the operator is controlling
It works with the documented 8-inch coupling loop and a fully extended support mast. The larger conductor path changes both radiation resistance and the coupling needed for a useful match.
Where people get into trouble
Using the booster cable with the small coupling loop or folding it into an improvised shape does not preserve the TOTAL configuration and can create poor or unstable tuning.
A repeatable field method
Fit the named radiator and coupling loop, keep them circular and coplanar, secure the feed line, tune at low power, and remember that this discontinued 3.0 accessory is not a 4.0 component.
These F-LOOP instructions preserve the documented discontinued CHA F-LOOP 3.0 system for existing owners. They do not transfer hardware, tuning, power, or compatibility claims to the separate pre-production CHA F-LOOP 4.0.
