Since the original question concerned a move from 50 to 100 feet, in my
experience a single 10 Meter antenna at 100 feet is almost always too
high to do much good.
Welllll, I think it also makes a difference where you are. Here in Northern
Minnesota I have a C31XR (7 el on 10) at 110', and a C4 (3 with 2 drivers on
10) at 55'. The high antenna seldom if ever is below the low one on 10.
Admittedly, it is a killer antenna on 10, one that actually allows me,
running 1500 watts, to often beat out stations on the east coast running 100
watts to a tribander at 30'. :-)
