   No, it wouldn't.   
      
   You're not looking at "delay" per se as in propogation delay   
   down a transmission line. You're simply looknig at the fact   
   that at those wavelengths, the line is acting as a simple   
   damped resonator.   
      
   In other words, all the bobonsense you read about lines   
   ignores that they are behaving just like a bass reflex   
   with a whopping big port, a tiny volume, and a lot of   
   damping.
