Thanks, gentlemen (Eddy, K8GG, ZR, Roy, Herb, et. al.), for all the
feedback on this. So, it seems it's pretty much what I expected --
if you tune an antenna for better results on one frequency, you
detract from its operation on another. Maybe one of these days I'll
get around to playing around with that 3/8 wavelength L anyway...
