About This Assembly
RG142 Cable
RG-142 is a double-shielded 50-ohm PTFE coaxial cable rated for operation from cryogenic temperatures up to +200°C with a 0.195" outer diameter. Its dual-shield construction provides excellent EMI rejection while the PTFE dielectric ensures stable electrical performance across a wide frequency range. The preferred choice for military, aerospace, and high-power RF applications.
N Connector
Type N is a threaded RF connector rated from DC to 18 GHz with a durable weatherproof design, making it the preferred interface for outdoor antenna installations, cellular base stations, and commercial wireless infrastructure. Its larger size compared to SMA allows higher power handling and the threaded coupling resists vibration, making it suitable for mobile and fixed outdoor 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 N and TNC cable assembly is well suited for high-temperature and high-power military or aerospace RF assemblies. The combination of reliable N and TNC 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, RG142 loses approximately 18.5 dB per 100 ft. This 6 ft assembly will have roughly 1.11 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 – 6 GHz. The effective frequency limit is set by the lowest-rated component — either the cable or one of the connectors. Both N 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.
