Great advice. And, of course, any end-fed vertical needs radials or a 
counterpoise. A year or so ago, I did a tutorial presentation on 160M 
with limited space. Nothing original on my part, simply showing the 
fundamental stuff about how antennas work, and pulling together lots of 
excellent work by others.  http://k9yc.com/publish.htm
