So I have settled on a 26-28' wire with a 16' 
counterpoise.  I found 
that a 24' wire working against a 16' 'poise would not

always load up on 
40m--it needs to be at an obtuse angle to the plane of

the counterpoise 
to tune well on 40m with the internal tuner.  In 
contrast, the 26-28' 
piece will tune to <2:1 on 40m even if strung 
carelessly over doors, 
picture frames, or whatever else is available (e.g. in

a hotel room with 
windows that don't open).  20 and 30m seem to tune 
fine with the 24'/16' 
ant, even if suboptimally deployed.

Question: Assuming both tune up about as well, do you 
think the 24' ant 
with a longer (33') counterpoise will radiate better 
on 40m than a 
26-28' ant with a 16' 'poise?  I realize there are 
many uncontrolled 
variables involved, but maybe it is simpler than I 
think?
