Specs Summary
About This Assembly
RFC100A Cable
RFC-100A is a cost-effective thin 50-ohm coaxial cable equivalent in size to LMR-100A, offering solid performance for short internal connections and pigtails at a lower price point. A practical choice for budget-conscious builds where cable runs are under 10 feet, such as WiFi module connections, GPS pigtails, and compact RF assemblies.
FME Connector
FME (For Mobile Equipment) is a miniature threaded RF connector designed for mobile and vehicle-mounted antenna applications, particularly at GSM, CDMA, and FM frequencies. Its small size and robust threaded coupling make it common on vehicle-mount antenna mounts, cellular signal boosters, and mobile broadband modems.
RP-SMA Connector
RP-SMA (Reverse Polarity SMA) uses the SMA threaded coupling mechanism but with the male/female pin convention reversed — the jack has a pin and the plug has a socket. Originally standardized to prevent connection of uncertified antennas to consumer WiFi equipment, RP-SMA is now the dominant connector on commercial WiFi routers, access points, and 2.4/5 GHz antennas.
Common Applications
This FME and RP-SMA cable assembly is well suited for short pigtails and budget compact RF device connections. The combination of reliable FME and RP-SMA connectors and custom-cut cable length makes it a practical choice for both field installations and bench setups. Every assembly is hand-terminated, continuity tested, and ships free within the USA.
RFC100A Signal Loss
Approximate attenuation at common RF frequencies.

| 900 MHz | 16.5 dB | 0.165 dB |
| 1.8 GHz | 24.5 dB | 0.245 dB |
| 2.4 GHz | 29 dB | 0.29 dB |
| 5.8 GHz | 49 dB | 0.49 dB |
Frequently Asked Questions
What is RFC100A coaxial cable used for?
RFC-100A is a cost-effective thin 50-ohm coaxial cable equivalent in size to LMR-100A, offering solid performance for short internal connections and pigtails at a lower price point. A practical choice for budget-conscious builds where cable runs are under 10 feet, such as WiFi module connections, GPS pigtails, and compact RF assemblies.
What is the signal loss of RFC100A?
At 1800 MHz, RFC100A has approximately 24.5 dB of loss per 100 ft (0.245 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 2 GHz, limited by the lowest-rated component across the cable and connectors.
What is a FME connector?
FME (For Mobile Equipment) is a miniature threaded RF connector designed for mobile and vehicle-mounted antenna applications, particularly at GSM, CDMA, and FM frequencies. Its small size and robust threaded coupling make it common on vehicle-mount antenna mounts, cellular signal boosters, and mobile broadband modems.
