That was basically the reason I went to the LMR 400 and 600 UF.  I 
wanted the better isolation and had lots of over a 1000 feet.
I've never liked Belden since lightning blew off the water proofing at 
the top of the tower and I ended up with water running out of the 
rig.    The damage was more to the desk than to the equipment and I 
realize Belden generally makes good coax, but that experience soured me 
on them.  I do have a 100 feet or so of 1/2" Heliax, but have found the 
1/2" to be too fragile and larger in the station would be a bit 
unwieldy.  I agree that the comscope would be a slightly better choice, 
but as I have rolls of both LMR 400 and 600 it wasn't "that" much better
