50ohm Coaxial Cable LMR200UF TEL300UF TEL400UF TEL600UF

The TELSTO series 50-ohm braided coaxial cables, including models LMR300, LMR400 (RG8U), LMR500, LMR600, LMR900, LMR240, RG58, RG213, 5D-FB, 8D-FB, 10D-FB, etc. are designed for high-performance RF signal transmission. Featuring a foam polyethylene (PE) dielectric and a bonded aluminum foil with tinned copper or aluminum alloy braiding outer conductor, this series guarantees a stable characteristic impedance of 50±2 ohms, along with low VSWR and low attenuation. Available with PVC, PE, or LSZH jackets, these cables operate reliably across a wide temperature range from -40°C to +85°C. They are ideally suited for various applications in telecommunications, broadcasting, wireless networks, and signal interconnection between electronic equipment.

Description

Key Design & Construction:

· Precise Impedance: All cables in the series maintain a stable 50±2-ohm characteristic impedance, ensuring minimal signal reflection and maximum power transfer in standard RF systems.

· Low-Loss Dielectric: At the core is a gas-injected foam polyethylene (PE) insulation. This construction significantly reduces dielectric losses compared to solid PE, enabling better signal integrity over longer distances, especially at higher frequencies.

· Superior Shielding: A dual-layer shield combining a bonded aluminum foil and a high-density (80%-95% coverage) tinned copper or aluminum alloy braid provides excellent protection against Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). This ensures signal purity in electrically noisy environments.

· Durable Outer Jacket: Options include PVC for general use, UV-resistant PE for outdoor applications, and Low Smoke Zero Halogen (LSZH) for installations with strict fire safety requirements, such as in public spaces, aircraft, or mass transit systems.

Applications

· Cellular Infrastructure: Connecting base station antennas to RF equipment (e.g., for 4G LTE, 5G).

· Wi-Fi and Wireless LAN: As feeder cables for access points and distributed antenna systems (DAS).

· GPS and Satellite Communication: For timing signals and satellite ground station connections.

· Two-Way Radio & Public Safety: Used in land mobile radio (LMR) systems, hence the common name for the category.

· Broadcast: Transmitting radio and television signals.

· Military & Aerospace: Where reliable, lightweight RF connectivity is critical.

· Test & Measurement: As reliable interconnects in laboratory and field testing setups.
