McDouglas worked hard to avoid requiring static wicks, too. They're fragile, and delays to change them are costly.
ADF and HF are the primary victims of P-static, but if it's bad enough, VHF can be affected, too.
I once was confronted with a Sabreliner where the VHF Comm would go away on liftoff. The diverter strips on the radome depended on a secure connection through the underside of the head of a single flat head screw. The mating surface was corroded.
