The inner silver plated flat strip shield coupled with higher velocity expanded PTFE tape dielectrics yield lower attenuation levels over operating frequencies.
LLS 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.
Special constructions are the norm rather than the exception, so please make sure you contact Harbour Industries sales@harbourind.com if you don’t see the specific construction for your application.

Attenuation CalculatorAlthough typical and maximum attenuation values at discrete frequencies may be found in Harbour's online catalog, this Attenuator Calculator makes it easy to compare multiple items at any operating frequency. Just type a frequency in MHz (for instance 18 GHz = 18,000 MHz) to calculate and compare typical attenuation values.
