• Inner conductor: 1.00 mm solid copper
• Dielectric: 4.6 mm foamed polyethylene
• Shielding: double (aluminium foil + tinned copper braid, 77% coverage)
• Outer jacket: LSZH, 6.9 mm diameter
• CPR class: B2ca-s1a,d1,a1
• Attenuation: 20.0 dB/100m @ 1000 MHz, 30.0 dB/100m @ 2150 MHz
• Reel length: 250 m

Why choose it

The B2ca fire classification makes this cable suitable for installations where building codes demand low fire propagation and smoke emission. Double shielding provides over 100 dB screening effectiveness, preventing interference in dense RF environments. The solid copper core ensures reliable DC powering for remote amplifiers or LNBs.

Ideal use cases

• Satellite IF distribution in hotels, offices, and apartment blocks
• Cable TV trunk lines and riser cables
• Long indoor runs where low attenuation is critical
• Installations requiring CPR B2ca compliance

Good to know

The cable is supplied on a 250 m reel without connectors, allowing custom termination. Minimum static bending radius is 35 mm. Velocity of propagation is 85%.
