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...

Hi Ed,

I agree with Denny 100%. Any loss in a tuner feeding the 24 ft vertical will be
less than that in the Bug Catcher. The major loss in the Bug Catcher is due to
the resistance caused by the turn-to-turn capacitance that makes the inductance
resonant at some frequency not too much higher than that that at the operating
frequency. See the resistance vs frequency curve of a parallel LC circuit, where
you'll see that the value of resistance is maximum at resonance, which is not
what you want at anywhere near the operating frequency.
