The /77 adds sprung RFI grounding fingers to the bayonet shell, giving continuous shell-to-shell bonding across the mated joint — the reason it is specified on radio, radar and databus harnesses that sit near transmitters. Shell 18 / 18-31 carries thirty-one size-20 contacts, the highest signal count in that shell. Note the trade-off: RFI plugs are rated 250 mating cycles rather than the 500 of the plain bayonet variant.
