Mike, LMR240 is about the size of RG8X, it is for inside jumpers between
shack equipment, such as watt meters and rigs.  If you want something the
approximate size of RG213, you want LMR400, and if you intend to direct bury
it, specify LMR400DB, which is specifically meant to be direct bury it.  If
the run is longer than maybe 150 feet, I'd recommend LMR600, or LMR600DB if
you are going to direct bury it.  LMR400 and LMR600 require different
connectors, so whatever coax you order, be certain to order the correct
connectors to fit it.  If you have any further questions on this, drop me a

Subject: Replacing my coax cable

Hi all: 

As I got to order some tubes from RF Parts, I'm looking at ordering some
replacement coax as well as the prices look pretty good. 
The problem is, I'm not sure on what to order as the site has such a variety
from Andrew Heliax to LMR600 and everything in between. 
I need a direct berry, low loss to replace my RG-213 and I'm wondering if
the LMR240 will do?  
I'm thinking that the LMR240 is a little larger than the 213 and that's what
those numbers mean. 213 = .213 of an inch, 240 = .24 of and inch and so on.
Therefore the LMR400 or 600 would be a pretty thick cable and may require me
to drill a larger hole to thread it. LOL 
My current PL-259s fit the exit hole of the shack.
