Topband: Where to place a preamp? Switching Beverages?

[Pete Smith N4ZR]

Thanks, everyone, for too many good inputs to list here.  A lot of good 
ideas, both for experimental approaches and for the final 
configuration.  At least for experimental purposes, I will go with the 
preamp in the shack and, assuming that my feedline is not quiet, 
significant improvements in management of common mode currents.  One 
correspondent advocated transformer coupling instead of common mode 
chokes, and I'll need to correspond further with him on that, because I 
don't understand quite how it would work.
