Foam-Flex 141 High Temp Resistant RF Coaxial Cable with Foamed PTFE Dielectric

The Foam-Flex 141 represents the premium tier of our low loss, high temperature resistant RF coaxial cable series. Engineered for mission-critical applications where signal integrity over distance and maximum power handling are non-negotiable, the 141 model leverages a larger conductor geometry combined with foamed PTFE dielectric. This robust construction delivers the absolute lowest attenuation and highest thermal efficiency in the Foam-Flex portfolio.

Designed to bridge the gap between rigid performance and flexible installation, the Foam-Flex 141 excels in dissipating heat generated during high-power transmissions, thanks to the superior thermal properties of its foam core. It maintains exceptional phase stability even under extreme environmental stress or mechanical flexing. Whether deployed in complex phased array radar systems, long-distance satellite uplinks, or high-energy broadcast transmitters, the Foam-Flex 141 guarantees uncompromising reliability and precision.

• Superior Phase Stability - The advanced foamed PTFE dielectric ensures the electrical length remains remarkably stable despite drastic temperature fluctuations, which is vital for phased array antennas and precision instrumentation.
• Ruggedized & Durable - Built to withstand the harshest field deployment conditions, offering exceptional tensile strength, crush resistance, and environmental sealing while retaining excellent flexibility.
• High Shielding Integrity - Features a multi-layer, high-efficiency shielding architecture that provides maximum isolation from external noise, ensuring absolute data purity in electromagnetically congested environments.
• Broad Frequency Consistency - Maintains a rock-solid 50 Ohm impedance and exceptionally low VSWR across the widest microwave frequency spectrum.

• Radar & Electronic Warfare - Delivers the precise phase stability and extreme power handling required for advanced defense avionics and ground-based radar systems.
• Satellite Communications - Ensures ultra-low-loss connectivity for high-power ground terminals and airborne platforms where every decibel of signal matters.
• Broadcast Transmitters - Ideal for feeding high-energy signals in professional radio and television broadcast infrastructure.
• Antenna Systems (DAS) - Perfect for extensive cable runs in stadiums, airports, and tunnels where minimizing signal attenuation over distance is paramount.
• RF Power Amplifier - Capable of handling the extreme output power of high-energy amplifiers without signal degradation or thermal breakdown.
• Precision Calibration & Metrology - Used in national labs and high-end field testing where cable loss must be perfectly predictable and minimized.

• Q: What sets the Foam-Flex 141 apart from the smaller 120 or 086 models? A: The Foam-Flex 141 is a heavy-duty model of the series. Its larger conductor geometry provides lower possible attenuation and higher power handling capability. It is the definitive choice for long-distance runs and high-energy systems where signal preservation is absolutely critical.
• Q: How does the foamed PTFE dielectric contribute to high-power performance? A: The foam structure's high air content significantly lowers the dielectric constant and dissipation factor. This drastically reduces the internal heat generated during high-power transmission, allowing the Foam-Flex 141 to handle extreme power levels without overheating or suffering from thermal breakdown.
• Q: Is the Foam-Flex 141 suitable for harsh outdoor or marine environments? A: Absolutely. It is constructed with premium, weather-resistant FEP jacket that provide outstanding protection against moisture, UV radiation, and extreme temperatures, making it perfectly suited for both outdoor towers and marine-based communication systems.
• Q: Can this RF coaxial cable maintain its flexibility despite its larger size? A: Yes. Despite its robust, heavy-duty construction, the Foam-Flex 141 retains excellent mechanical pliability. It can be routed through tight equipment racks and complex enclosures with ease, simplifying installation compared to traditional semi-rigid alternatives.
• Q: What connector types are compatible with this RF coaxial cable for custom assemblies? A: We specialize in manufacturing custom cable assemblies for the 141 model. It can be terminated with a wide range of high-power and precision connectors, including N-Type, 7/16 DIN, SMA, and TNC, to meet your exact system interface requirements.
• Q: Is the RF coaxial cable RoHS compliant? A: Yes, our standard Foam-Flex 141 cables are fully RoHS compliant. The materials used are designed to withstand high temperatures, making them fully compatible with modern manufacturing processes.
• Q: Do you provide detailed electrical datasheets for system modeling? A: Yes, we provide comprehensive technical datasheets containing full electrical and mechanical specifications (including attenuation charts, power ratings, and bend radius data) to assist your engineering team with accurate system modeling and design.
• Q: What is the typical lead time for bulk orders of the Foam-Flex 141? A: Lead times vary based on current inventory and order volume. Standard bulk cable is often available for quick shipment, while custom high-power assemblies typically require a standard production lead time.
