I used LMR-400UF around the rotators for years.  It worked very well.  I did need to replace one
length due to a broken center conductor, but that was after years of heavy use.  When I rebuild my
array, I bought some 9913F (sometimes called 9913F-7 or 9913F7).  Same electrical specifications as
LMR-400UF, +/-, and noticably more flexible to handle.  It has only been up for about 2 years, but so
far, so good.  I also use it for the mode-L loop to the helix from the hard line feed to the shack.

Shameless plug for an AMSAT Journal advertiser:  The folks at The RF Connection, www.therfc.com, were
very accommodating and knowledgeable.
