I have at 2400mhz too! Down around DC (sub 30mhz) your "pin"
is a short and the effects are mostly (though measurable) a shorted
coax with all the effects as expected. As you get up there in
frequency the "short" as described doesn't behave as it did at DC.

The problem is similar to another thread concerning real world
components where the discussion finally recognized that like other
real world components a short is not always what it may look like.
