[600MRG] 630 with a 68ft vertical?

[Gedas]

WAG here but I would venture to say if you had that antenna and drove it 
with 30W or so you will not have any trouble making QSO's all over NA 
given "normal" conditions. Make the coil HUGE in dia (like 8-10 inches) 
and of large AWG (like #6 - #8 etc copper wire) to minimize losses and 
you will have a blast. See if you can bring down a pair of wires from 
the top, spaced 180 degrees apart down at an angle to add a capacity 
hat. If you can make them 50' or so that will help a lot.
