With a decent top hat, the bottom fed 24 foot will outplay the shorter
antenna... For this installation the SGC auto tuner should work
satisfactorily... I would go this route over the Bug Catcher,
myself...

Consider some roll out radials clamped to the ground tap on the
antenna feed for when you are able to lay wires across the ground -
like after midnight... This will make a major improvement...
