Sat phone antenna co-ax cable

I am installing an external marine passive antenna for my 9505 Iridium phone.
The run from antenna to phone will be about 11 meters, maybe 12.
What is the best type/brand of co-ax to use to minimize signal losses?
Something as thick as RG213 would be very difficult to run where I have to put it, so diameter about 5mm would be great.

Re: Sat phone antenna co-ax cable

LMR400 is probably the best bet for loss and cost at that length and frequency. One thing I'd do is get a smaller cable, like LMR240, about 1 meter long and use that to attach to the antenna adapter. The other end would go to the larger cable. Trying to use a handheld with a big unruly cable sticking out the back is a pain and puts a good bit of stress on the adapter. 5-10 feet of the smaller cable will not add too much loss to the overall power budget and will reduce tension on the adapter and connectors.
