Think about it George,

The antenna doesn't care what size airplane it's on, but different sized
(flat plate drag) airplanes use differing amounts of thrust force to go
the same speed. The thrust-drag balance determines speed. If you add 5
lbs of drag to an airplane that only makes 10lbs of thrust you change the
cruise speed more than you would for an airplane that makes 500lbs of
thrust to go the same speed. A 757 would care not about one more comm
antenna when running 200kts (indicated), but a Lancair Legacy would notice
it quite a bit. It's all about the relative drag vs. thrust balance.
Cheers,

Matt-

Or is that Cheers Matt (to me)?

Not sure what your talking about, but I wrote or
