Low Loss Cable Assemblies

Low Loss Cable Assemblies

Signal loss is the ultimate adversary of any RF system. Our low-loss cable assemblies are engineered to combat attenuation at every critical node—from the raw conductor material to the connector interface. Built with high-purity silver- or tin-plated copper conductors and closed-cell foam PE or PTFE dielectrics, each assembly features multi-layer shielding that delivers an exceptional shielding effectiveness of over 90 dB. By minimizing power dissipation within the cable, we ensure maximum signal integrity reaches your antenna, receiver, or test equipment.

We support diverse system architectures with a comprehensive size spectrum, ranging from compact 100-series jumpers to heavy-duty 600-series feeder cables. These can be terminated with the precise connectors your application demands, including N, SMA, TNC, BNC, 7/16 DIN, and more.

Furthermore, every assembly undergoes rigorous phase-matching and VSWR testing, built to your exact length specifications. Whether you require a single high-frequency assembly for a laboratory bench or thousands of custom coaxial assemblies for a large-scale network rollout, you can count on the same repeatable, high-tier performance, order after order.

Why Choose Our Low Loss Cable Assemblies

Genuinely Low Insertion Loss

We select dielectric and conductor materials specifically to minimize attenuation, not just to meet a minimum spec. As a result, that translates into a stronger signal at the far end of every run, especially on longer cable lengths.

Stable Across Frequency and Temperature

Our assemblies hold their VSWR and phase performance from sub-1 GHz signals up through several GHz, and across an operating range of -40°C to +85°C. In other words, cold mornings and hot rooftops don’t change the numbers.

Rugged, Field-Ready Builds

Together, UV-resistant, LSZH, or armored jacket options, tight bend radii, and crush-resistant construction mean these cables survive real installation environments — not just a datasheet.

100% Tested, Every Assembly

We sweep-test insertion loss and VSWR on every finished assembly before it ships, not just on a sample batch. So you get a test report, not just a promise.

Fast Turnaround on Custom Orders

Because we control cable, connectors, and testing in-house, we cut custom low loss coaxial cable assemblies to your exact length and configuration without the long lead times of a multi-vendor supply chain.

Broad Compatibility

Our low loss RF cable assemblies work as drop-in replacements across the industry’s most common cable classes. As a result, you rarely need to redesign your system to use them.

Technical Specifications

Attenuation by cable size class (typical, dB per 100 ft / dB per 100 m, at 25°C)

As a rule of thumb, the larger the cable class, the lower the loss — but also the less flexible and more expensive it becomes. That’s why we can help you pick the smallest cable that still meets your loss budget. Still, exact figures vary slightly by construction and jacket type, so treat this table as a starting point and ask our team for a datasheet matched to your configuration.

Applications

Low-loss cable assemblies are the lifeline of critical RF infrastructures where link margins are tight and every fraction of a decibel matters. Our custom solutions are widely deployed across key industries:

• 5G & Wireless Infrastructure: Powers base stations, small cells, and Distributed Antenna Systems (DAS), preserving vital signal budget between radios and antennas.

• Broadcast & Telecom Systems: Optimizes two-way radio towers and WISP backhaul links by drastically reducing attenuation, ensuring transmit power reaches the air rather than dissipating in the cable.

• Military & Defense: Engineered for mission-critical communications, electronic warfare (EW), and navigation systems, maintaining flawless RF performance under severe shock, vibration, and thermal extremes.

• Aerospace & UAVs: Delivers high-frequency performance in a lightweight, space-saving footprint, ideal for weight-sensitive airborne and unmanned platforms.

• SATCOM & Ground Stations: Ensures stable phase characteristics and ultra-low attenuation for ground stations and VSAT terminals, safeguarding link margins at microwave and millimeter-wave frequencies.

• Advanced Radar Systems: Provides precision phase-matched assemblies to maintain impeccable timing accuracy across multi-channel arrays, a necessity as modern radar bandwidths expand.

• Test & Measurement: Supplies laboratory and production-line testing with highly repeatable, stable connections to eliminate cable-induced measurement errors.

• Industrial IoT & SCADA: Protects fragile link budgets in remote monitoring networks during long, punishing outdoor cable runs to sensors and telemetry radios.

Custom Low Loss Coaxial Cable Assemblies

Because no two installations are identical, we can build low loss cable assemblies to order:

• Length — cut and terminated to your exact specification, from a few inches to hundreds of feet
• Connector type, gender, and orientation — straight, right-angle, bulkhead, and reverse-polarity options across N, SMA, TNC, BNC, 7/16 DIN, and more
• Jacket material — standard PE, UV-resistant polyethylene, LSZH for indoor fire-safety codes, or armored jacketing for direct burial and harsh environments
• Shielding level — standard braid-and-foil or enhanced multi-layer shielding for high-EMI environments
• Phase and amplitude matching — matched sets for multi-channel and array applications
• Testing and documentation — insertion loss, VSWR, and continuity test reports shipped with every batch
• Labeling and packaging — custom tags, length markers, and packaging suited to your installation crew or production line

Simply tell us your frequency, power, and environmental requirements. Then, we’ll recommend the cable class and connector combination that fits — no unnecessary upsizing, no compromise on loss.

FAQ

1. What is a low loss cable assembly?

It’s a coaxial cable assembly built specifically to minimize signal attenuation as RF or microwave energy travels along it. To do this, low loss designs use premium conductors, low-loss dielectrics, and effective shielding to keep more of your transmit power — or received signal — intact from one end of the cable to the other.

2.Where can I find low-loss cable assemblies for demanding applications?

You’re looking at one source: we design and build low loss cable assemblies for telecom, military, aerospace, and test-and-measurement applications, with in-house testing on every unit. In particular, if your application involves long runs, high frequencies, or harsh environments, just tell us the requirements and we’ll recommend a configuration.

3.Can you build custom low loss coaxial cable assemblies to my specifications?

Yes. We build to length, connector type, jacket material, and shielding level on request. Simply send us your frequency, power, and environmental requirements, and we’ll quote a custom build — no minimum order size required for most configurations.

4.Do you offer low loss SMA cable assemblies, or other connector types?

Yes. SMA is one of our most common terminations, alongside N-type, TNC, BNC, 7/16 DIN, and 4.3-10. In addition, we support straight, right-angle, and bulkhead versions in male and female configurations.

5.How do you test each low loss cable assembly before shipment?

Every assembly goes through insertion loss and VSWR sweep testing before it ships. For phase-matched or multi-channel sets, we also verify amplitude and phase tracking across the unit’s frequency range, and we can provide test reports with your order.

6.How do I choose the right cable size for a high-frequency low loss cable assembly?

It comes down to your loss budget and physical constraints. Specifically, larger cable classes (like 400-series or 600-series) carry less loss but are stiffer and heavier, while smaller classes (like 195-series) are easier to route but lose more signal over distance. So, tell us your run length, frequency, and available space, and we’ll recommend the smallest cable that still meets your performance target.
