to go to ~100 feet for a single-tower station, and to put the 40M
beam on top. I did it, and have been glad I did.

see what the arrival/takeoff angles will be.
But aside from that, 100' gives you a sweet spot on 20M and lower
arrival/takeoff angles on 40. A small tribander at 40-50' on a side-mount will
