The trouble with the 450 ohm line is that you have a balanced line
with an unbalanced load.  You would like to put a balun or common-mode
choke at the antenna end, but that is impractical.  Thus the line
will have substantial radiation and probably will warm the worms.
Also, 450 ohm window line is NOT really weatherproof, as has been 
reported by reliable sources.  Maybe you used true OWL which would be.
