Description

Product Description

Overview

JBY195-LSFH is a flexible, low loss 50 ohm coaxial cable with a
low smoke, halogen free (LSFH) outer jacket. It is the LSFH version of the
popular JBY195 195-series cable, offering similar electrical performance and size, but with a
low smoke, zero-halogen jacket that is better suited to indoor installations, public buildings,
and other environments where fire and smoke performance are important.

Electrically, JBY195-LSFH is a 195-size 50 ohm RF cable designed for use up to around
6 GHz, with significantly lower loss than standard RG58 and with
good shielding effectiveness (>90 dB). It works well for short to medium RF runs,
pigtails, jumper cables, test leads, and general RF interconnects.

Key Features

50 ohm low loss, 195-series cable – suitable for a wide range of RF and microwave applications.
LSFH jacket – low smoke, halogen free outer jacket to reduce toxic emissions in a fire.
Flexible construction – solid bare copper centre conductor, foamed PE dielectric, aluminium foil and tinned copper braid.
Good shielding – typical shielding effectiveness better than 90 dB.
Wide operating range – DC to 6 GHz with typical use up to around 3 GHz.
Compact size – approx. 3.44 mm over braid and 4.95 mm over the jacket.
Per-metre ordering – order exactly the length you need; continuous lengths supplied wherever possible from stock reels.

Typical Applications

Indoor RF links and distribution systems
DAS (Distributed Antenna Systems) and in-building coverage
Short to medium length antenna feeder runs
Lab and test-bench interconnects and patch leads
Custom cable assemblies using standard 195-series (RG58 / JBY195) connectors
Equipment jumpers, pigtails and OEM harnesses

Construction Details

From the centre outwards:

Centre conductor: solid bare copper, approx. 0.95 mm (0.037 inch) diameter.
Dielectric: foamed polyethylene, approx. 2.87 mm (0.113 inch) diameter.
Outer conductor: aluminium tape shield with an overall tinned copper braid (double shield).
Diameter over braid: approx. 3.44 mm (0.135 inch).
Outer jacket: low smoke, halogen free (LSFH), approx. 4.95 mm (0.195 inch) overall diameter.

Connector Compatibility

JBY195-LSFH is the same size family as JBY195 and RG58, so it works with standard
195-series / RG58 style crimp and clamp connectors (SMA, N, TNC, BNC etc.) that specify
compatibility with JBY195 or JBY195-LSFH. This makes it straightforward to build
custom assemblies using the existing range of 195-series connectors stocked by RFShop.

Compliance and Notes

RoHS compliant cable construction.
Low smoke, halogen free (LSFH) jacket for improved fire performance and reduced toxic fumes.
Supplied from stock reels; continuous lengths shipped where possible. If you need a specific cut pattern or pre-terminated assembly, please contact us.
