Usually "direct burial" cable is just a PE jacket with a flooding compound in the braid.
Times Microwave makes a direct burial variant of their LMR-400 called "LMR-400-DB". It adds a flooding compound in the braid. The flooding compound will seal small fractures in the jacket. BTW, for everyone, there is a new "dry" type of water blocking compound used in fiber optic cables that is usually in the form of a powder or a yarn. When it gets wet it expands and seals the damaged cable area. It's lots easier to work with than the more traditional gel-type flooding compounds. Maybe if we're lucky we'll see someone start making coax that way! -Bill > -----Original Message----- > From: Topband [mailto:topband-boun...@contesting.com] On Behalf Of > mstang...@comcast.net > Sent: Tuesday, June 03, 2014 10:10 AM > To: topband@contesting.com > Subject: Topband: 50 ohm direct burial coax cable > > Does anyone know of a source for 50 ohm "RG-8" type direct burial coax > able. > > I can find many sources for CATV and Satellite 75 ohn cable but not 50 ohm. > > Direct burial cable is coated with and anti-fungal compound.
