Hi, I have an SG230 ATU connected to a Kenwood TS-2000 (with remote head) for mobile use.
I am making up 2 x 5 foot lengths of RG58 as balanced feeder for a miniature loaded doublet on the roof of my Merc (16 feet, copper wire, mildly helically wound carbon-fibre sail-board mast). Thye feeding principle is similar to this article: http://k9zw.wordpress.com/2008/08/02/ladder-line-building-pass-through-with-twin-coax-rg-8/
Question, should I connect the earth strap across the two coax lines to a) my car ground (negative earth), b) the ground lug on the SG230 or c) Leave it floating?
Thanks for your consideration.
