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.
UHF Connector
The UHF connector (also known as PL-259 male / SO-239 female) is a large, low-cost RF connector designed in the 1930s for HF and VHF frequencies. Despite its name, its practical usable range is below 300 MHz due to its non-constant impedance design. It remains extremely popular in amateur radio (HF through VHF), CB radio, and marine radio applications.
Common Applications
This UHF cable assembly is well suited for short pigtails and budget compact RF device connections. The combination of reliable UHF 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.
Frequently Asked Questions
Is this cable hand-assembled in the USA?
Yes. Every CoaxRF cable assembly is hand-terminated and continuity tested at our US facility before shipping. We do not drop-ship pre-made cables from overseas — each cable is built to order.
Can I order a different length than 50 ft?
Yes. This page is for the 50 ft assembly. Use the length buttons above to select a different standard length, or use the Cable Builder for any custom length.
How much signal loss will I see with this 50 ft cable?
At 1800 MHz, RFC100A loses approximately 24.5 dB per 100 ft. This 50 ft assembly will have roughly 12.25 dB of insertion loss at that frequency. See the signal loss table for all frequency points.
What is the maximum frequency for this assembly?
This assembly is rated DC – 300 MHz. The effective frequency limit is set by the lowest-rated component — either the cable or one of the connectors. Both SO239 UHF Female and SO239 UHF Female connectors must be within spec at your target frequency.
What is your return policy?
We accept returns within 30 days of delivery. Custom-length cables are accepted as long as they are in original condition. Contact us and we will provide a prepaid return label at no charge.
