"I didn't know they had wifi back in the day."
"They didn't! That's the beauty of the pin, it uses UHF to search for data."
Antoine Triplett and Skye[src]

The UHF Pin is one of Antoine Triplett's grandfather's Howling Commando items, a device that is used to search for data disguised as a pin.


Antoine Triplett retrieved his grandfather's Howling Commando gear and offered it to Phil Coulson as a tactical advantage during the undercover investigation on Cybertek and the missions to come. The UHF Pin was among these items.

Melinda May activated the UHF Pin when she infiltrated Cybertek Corporate Headquarters in Palo Alto with Coulson, in order to give Skye access to the facility's computers to learn more about Deathlok.

Skye was confident that no one would notice her hacking since a UHF channel is so antiquated, it is not monitored. However, the attempt failed because the facility only used hard files kept in file cabinets, not computers.[1]
