[TowerTalk] Which type of cable for a crank-up tower?

[Dan Levin]

Of course, if I knew who made it I would just get the manual and do what they say.  But I don't know who made it, so...

I have an unidentified 65' crank-up tower, believed to be of English origin.  It needs to be recabled.  The existing (original) cable appears to be 5/16", but it might be 8mm or even 7mm (I am not where the tower is, so I can't measure it exactly).  Definitely bigger than 1/4".  The tower lives in a very salty, island climate.

I am trying to figure out what type of cable to use - not which size, but which material and construction.

The easiest thing to find that seems appropriate is 5/16" 7x19 galvanized steel.

But, I have read that these towers usually use 6x19 LC (linen core) - which I can find in plain steel, but not in galvanized.

1) Is galvanized the way to go in this situation?

2) Any sense of which construction is most appropriate?  I assume 7x19 would be best if I can't find the 6x19 LC.

3) Anyone have a source of 6x19 LC galvanized 5/16" cable?
