JEFA Tech Low Loss 400FR Coax - 250 ft. Reel
Part Number: LL400FR-B250
This cable is the same as Low Loss 400 with the addition of FR (flame retardant) rated LSZH (Low smoke zero halogen) jacket.
Benefits of Using LSZH cables
- LSZH cables are flame-retardant
- LSZH cables produce no halogens during a fire, making them less toxic for humans and the environment. This makes them different from other types of flame-retardant cables. Exposure to halogens harms the environment and lungs of people and other mammals.
- Self-extinguishing jackets of LSZH cables prevent the fire from spreading further.
- LSZH cables are UV resistant
Downside to LSZH vs non-LSZH
- There is no downside. LSZH is an upgrade to the jacket material. LSZH is required for some applications and there is no downside to having LSZH jacket vs a non-LSZH jacket.
Specification Highlights
- 50 Ohm Low Loss Coax
- .405" outer diameter (same as LMR-400, RG-8, RG-213) - connectors for these types of cable will fit
- LSZH UV resistant jacket
- Solid Copper Clad Aluminum Center Conductor
- Direct Burial Rated - no conduit needed
- Foam Dieletric - adds to flexibility and performance
- Double Shielded for low loss and interference rejection
