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.
