Eric,

Life is too short for this.  If you are trying to run multiple dipoles 
in a confined space or other odd setup,  why not try removing all but 
one, and concentrate on ggetting that one to work.

I know the tuner on the Kenwood has a pretty good matching range, so I'd 
try that radio first and be sure you are connected to the correct 
antenna pigtail on the radio.

  Hy power (and most of the antenna companies)  cut their antennas  long 
to start with and you probably need to shorten things up.   I'd try 
shortening about 3 inches off each end.  No need to cut anything, just 
unwrap the  wire at each end insulator, move the insulator 3 inches up 
the wire, and rewrap the  wire tail.   Without a swr  meter or analyzer 
it's hit or miss, but if the radio's tuner is all you have to go by, 
that's all you can do.

I'd do tuning tests  at a couple points in each of the bands 20, 17, 15, 
12, and 10.  You may get lucky with  a particular antenna length  on a 
particular band.


I'm not sure how high the 480's swr meter reads, but even a sighted  non 
ham could  tell you what shows on the meter.

Of course, you should be sure all coax and connectors in the system are 
in good shape.

As for the cw auto tune on the 480:  In cw mode,  rough tune the station 
and hit the cw tune button, which is  the lower of the 4 buttons in the 
  diamond pattern, just to the right of the number pad.   It won't work 
if either the cw bandwidth or shift are set too wide.   Set the shift at 
850, and the bandwidth  at 500 or lower and it will work.
