Commercial RF Coax Cables — Tower, DAS & Repeater Assemblies

Commercial RF installations must perform reliably for years in demanding environments. The right cable minimizes feedline loss, handles your power levels, and survives weather and UV exposure. N-type connectors are the outdoor commercial standard.

Signal Loss Comparison

dB loss per 100 feet — lower is better. Multiply by your run length and divide by 100.

Frequently Asked Questions

What RF cable is used for commercial cellular and repeater installations?

LMR-400 is the industry standard for commercial cellular booster and repeater feedlines. For runs over 150 feet, LMR-600 provides lower loss. RFC-400 and RFC-600 offer similar performance at a lower cost.

What connectors are used for outdoor commercial RF?

N-type connectors are the standard for outdoor commercial RF. They are weatherproof, handle up to 300W, and are rated to 11 GHz. 7/16 DIN connectors are used on high-power broadcast and large cell site equipment.

What is a DAS cable?

A Distributed Antenna System (DAS) cable carries RF signal from a central source to multiple antennas throughout a building. LMR-240 and RFC-240 are common for in-building DAS trunk lines, with LMR-400 for longer remote antenna unit runs.
