About This Assembly
1.13 Cable
1.13mm coaxial cable is an ultra-miniature 50-ohm cable used primarily for internal RF wiring in compact wireless devices such as laptops, tablets, and embedded modules. Its extremely small 1.13mm outer diameter allows it to pass through tight spaces inside consumer electronics, connecting antennas to WiFi or cellular modules with minimal signal loss over short distances.
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.
TNC Connector
TNC (Threaded Neill–Concelman) is the threaded version of BNC, offering improved performance up to 11 GHz and better vibration resistance through its screw coupling. It is commonly used in mobile radio antennas, avionics, and outdoor installations where BNC's bayonet lock would not provide sufficient mechanical security.
Common Applications
This TNC and UHF cable assembly is well suited for internal WiFi and cellular module antenna connections in laptops and tablets. The combination of reliable TNC and 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 6 ft?
Yes. This page is for the 6 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 6 ft cable?
At 1800 MHz, 1.13 loses approximately 38 dB per 100 ft. This 6 ft assembly will have roughly 2.28 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 TNC MALE 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.
