Commonly used radio frequency cables in WLAN systems are? (Multiple choice)

Question

Options

• ARG-8 jumper wire
• B1/2 (inch) superflex feeder
• C1/2 (inch) feeder
• D13/8 (inch) feeder

• A
  83% (40)
• D
  17% (8)

Explanation

RG-8 jumper wire, 1/2-inch superflex feeder, and 1/2-inch feeder (A, B, C) are the standard RF cable types used in WLAN deployments because they offer the right balance of signal loss, flexibility, and practicality for typical indoor/outdoor Wi-Fi antenna runs. RG-8 is a reliable coaxial cable used for short jumper connections between equipment, while 1/2-inch feeders (both rigid and superflex variants) are industry-standard choices for runs from radio equipment to antennas due to their manageable size and acceptable attenuation at 2.4/5 GHz frequencies.

Why D is wrong: The 1-3/8 inch feeder is a very large, rigid, and expensive cable designed for high-power applications like cellular base stations and broadcast towers - it is impractical and oversized for WLAN systems, which operate at much lower power levels.

Memory tip: Think of cable size matching system scale - WLAN is small-scale Wi-Fi, so it uses small-to-medium cables (RG-8, 1/2-inch). The 1-3/8 inch cable belongs to big, high-power cell towers. If the cable is wider than your thumb, it's not for your Wi-Fi.
