     I don't know. Did anything change? It's been my experience that different
baluns on the same antenna sometimes have an influence on SWR - sometimes
making it better and sometimes worse.

     What's the power rating of the Bencher? The original voltage-type Hy-Gain
balun is the BN-86 which had a power-related reputation. The new current-type
is the BN-4000B - it's rated at 4000 watts.

      It's been my experience that a couple of inches more wire doesn't make a
lot of difference. (With the exception of Mosleys, that is.)

     If the new balun looks fine SWR-wise and doesn't blow up, then everything
is okay. You may want to have a standby balun available just in case. I might
suggest the Force 12 B-1 baluns. They're a stacked toroid-type of balun and
are manufactured in a vaccuum chamber which means that all air is evacuated
and they're sealed against everything. They're $39.95. TOWER TECH has them.
