Wi-Fi 7 and 6 GHz: What Changes for Antenna Cables and Connectors
A designer upgrades a Wi-Fi 6 access point to Wi-Fi 7, keeps the same 25 cm U.FL pigtails and the same dual-band antennas, and sees throughput on the 6 GHz band 30 percent below the module vendor's reference. The radio is fine. The antennas do not … More

5.8 GHz FPV and Drone Video: Cable and Connector Guide
For 5.8 GHz FPV video, use the shortest practical 50 ohm assembly with the exact transmitter and antenna interfaces, verified loss over the operating band and supported strain relief. Connector polarity and antenna polarization are separate checks:… More

RG142 and RG400 Cables: FEP High-Temperature Coax Explained
RG142 and RG400 are nominal 50 Ω coaxial cable families commonly built with PTFE dielectric, FEP jacket and two silver-plated copper braids. A key difference in common constructions is the center conductor: solid silver-plated copper-clad steel in … More

Crimp vs Solder vs Clamp: RF Connector Termination Methods Compared
A production line makes hundreds of antenna leads. A field technician repairs one cable at a remote site. A microwave engineer terminates semi-rigid coax. The right termination method differs because cable construction, tooling and inspection are d… More

Coaxial Cable Attenuation Chart: RG58, RG316, RG174, RG213, LMR (dB/m at 8 Frequencies)
You are choosing between RG316, RG58 and LMR-240 for a 2.4 GHz run and want the loss numbers on one page, not scattered across seven datasheets. This chart gives approximate attenuation in dB per meter for the common RG and LMR cables at eight freq… More

RF Connector Frequency Limits: Complete Reference Table (SMA to 1.85mm)
A design review catches a problem: the layout uses SMA connectors on a 28 GHz link. SMA is not specified for 28 GHz, and the test lab will need a different series. A single reference table of connector frequency limits would have caught it on day o… More

Coax Selection for 5G Sub-6 Bands (n77/n78): What Changes at 3.5 GHz
Choose n77/n78 coax from its complete-assembly loss and matching across the actual operating band, not from a 3.5 GHz spot check alone. n77 spans 3.3 to 4.2 GHz and n78 spans 3.3 to 3.8 GHz, so a cable specified only at the nominal center can miss … More

RG178 and RG196 Micro-Coax: Ultra-Miniature Cable Guide
RG178 and RG196 are miniature nominal 50 Ω coaxial cable families used when an RF connection must fit a small route. The exact jacket, diameter and ratings vary: the RG178 reference here is 1.8 mm FEP-jacketed cable, while RG196 examples include 1.… More

mmWave Interconnects 24-40 GHz: Cables, Connectors and Cost Reality
For a 24 to 40 GHz coax interconnect, specify the complete assembly through its highest required frequency, with a suitable precision interface and defined insertion-loss and matching limits. A 2.92 mm interface is rated to 40 GHz as a connector fa… More

Coaxial Cable Diameter and Weight Chart: Every RG and LMR Series
A harness designer needs to route eight RF cables through a 25 mm conduit and keep the bundle under 600 g. Datasheets list diameter and weight in different units, and every maker rounds differently. A single chart helps: outside diameter in millime… More
