Just tie a knot at that point.

Isn't that a differential-mode choke?


You can make a very good HF common-mode choke by deliberately resonating
the inductance of a coil of coax with its self-capacitance... so it
seems to follow that a resonant UHF common-mode choke can be made by
tying the coax into exactly the right knot.

Don't know if it's of any practical use, but it isn't a completely April
Fool idea.
