 Hi Wally,   I  agree with Steve's comment below.  If you want to use 9913 and
then a more flexible cable  for the rotator area, you could use the 9913 as
long as you set up the 9913 to spiral upward during crank up (like a "slinky"
with the tower in the middle).  For a little more per foot, you would relieve
any of these concerns, including the spliced rotator loop,  by using "BURY-
FLEX" Tm which I designed to meet three criteria:  Low Loss, Rugged/abrasive
resistant (polyethylene) jacket and buriability, if need be.  It is important
to note "if need be" because "BURY-FLEX" Tm is not solely applicable to
buriable applications and does have a longer life than PVC'd RG 213, 8, 9913,
etc.  Also, "BURY-FLEX" Tm uses standard N's, UHF's, and adaptive terminators.
Another ref. to 9913:  I would suggest you obtain a sample of this equivalent
which you mentioned from that supplier, as well as a sample from us or
Wireman, and anyone else, before you make your choice.  The sample should be
at least three feet, and free of charge.   If I can be of any further help,
just let me know.  Any Tower Talkians who wish "BURY-FLEX" Tm samples are
welcome to contact us or The Wireman, Inc.   Cheers,  Steve Davis,  K1PEK

<...Ref: 9913 coax. I am looking at the "cable experts" 9913 equivilient for 
some of my vhf antennas. I use a hygain 70 foot crankup tower, and would 
like to use hardline, but realize it isnt practical. Is 9913 OK to use 
on a crankup these days?? I used a run or two of Belden 9913 years ago 
when it first came out, and seemed to work out well. Wondered if any of 
the specs changed and if it is still OK to use?>


 << Hygain specifically recommends AGAINST 9913 for it's TH11DXX, anybody 
  know why? >>
 
      They recommend against using it for the rotation loop only. That's
 because of the solid inner conductor will break when flexed excessively.
