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.

Sigh...
I can't differentiate between you and that other chap on this issue.
You both cite perfectly legitimate grounds and come to entirely
separate conclusions. You can't both be right, but neither of you seem
to be wrong!
Can we focus down on *one* issue to avoid disappearing up our own
backsides: as far as the tx is concerned, is the portion of the feed
line beyond the pin relevant at all or does it effectively cease to
exist, as would be the case at VLF/DC?
