I'm not familiar with that model, but I have a 40" Samsung LCD that is 
about 2 years old I'd have to look up the model number.  The two TV 
antennas (with remote preamps) are within about 10' under the tribander 
and within 10-15' of the 160, 75, and 40 meter antennas. I run the legal 
limit on all. They are within about 30' of the 144 and 440 arrays.  No 
interference except when the 144 array aligns right up with the South 
pointing TV antenna.and then it's mild.  BTW the RG-6 runs to the tower 
in the same conduit as the LMR-600 feed lines. It's also bundled with 
the feed lines going up the tower.
