LLS (Low Loss Spiral Shield) Coaxial Cable

Low Attenuation Cables

The inner silver plated flat strip shield coupled with higher velocity expanded PTFE tape dielectrics yield lower attenuation levels over operating frequencies. LLS (Low Loss Spiral Shield) Coaxial Cables are smaller and lighter weight than comparable LL flat strip braid constructions. Return loss improved by minimizing inherent spikes from the strip braid and interlayer.

Shielding Effectiveness levels have been measured at <-110dB

Special connectors have been designed and are readily available.
