Icom makes a little gizmo to allow you to plug a handheld into an
existing antenna from a panel-mount radio. Does anybody know what the
part number for this is? I've searched the Icom web site and can't find
any mention of it, but my avionics guy says it exists. Does anybody
have a part number?

Yes, I know you can make one yourself for less, but for political
reasons I want to buy it from a well known manufacturer.
