50ohm Coaxial Cable LMR300 LMR400（RG8U） TEL500 TEL600 TEL900

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.
