About This Assembly
Specs Summary
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.
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 N and UHF cable assembly is well suited for high-temperature and high-power military or aerospace RF assemblies. The combination of reliable N 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.
Signal Loss — 25 ft
Approximate insertion loss for this 25 ft RG142 assembly at common RF frequencies.

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 25 ft?
Yes. This page is for the 25 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 25 ft cable?
At 1800 MHz, RG142 loses approximately 18.5 dB per 100 ft. This 25 ft assembly will have roughly 4.63 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 N FEMALE and PL259 UHF 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.
