LMR240-UF, Jumper Cable N-Male to N-Male, 0.5ft
LMR240-UF Ultra-Flexible Coax Cable — High Performance Without the Bulk
Upgrade your coax without dealing with the size and stiffness of traditional heavy coax. LMR-240UF (Ultra-Flex) is an excellent choice for CB, 10-meter, amateur radio, scanner, and other RF installations where you want lower signal loss, excellent flexibility, and a manageable cable size.
Compared with common RG-58, RG-8X, and traditional RG-8, LMR240-UF provides an excellent combination of performance and ease of installation.
Why choose LMR240-UF?
Lower loss than RG-58 and RG-8X — More of your transmitter's power reaches the antenna, and more received signal reaches your radio.
Similar convenient size to RG-8X — LMR240-UF is approximately 1/4-inch diameter, making it much easier to route than large coax such as RG-213.
Ultra-Flexible construction — The stranded center conductor and flexible jacket make LMR240-UF especially well suited for mobile installations, jumpers, base-station equipment, and locations requiring tight bends.
50-ohm impedance — Designed for RF applications including CB, 10-meter and amateur radio equipment.
Excellent upgrade for RG-58 and RG-8X installations — Get improved transmission-line performance without jumping to a much larger cable.
How Does It Compare?
Cable | Approx. Diameter | Flexibility | Relative Loss | Best Use |
RG-58 | 0.195" | Excellent | Higher | Short/light-duty runs |
RG-8X | 0.242" | Excellent | Moderate | CB/mobile/general use |
LMR240-UF | 0.240" | Excellent | Low | Premium mobile & medium runs |
RG-8 | ~0.405" | Moderate | Low | Larger base-station runs |
RG-213 | ~0.405" | Fair/Moderate | Low | Long/heavy-duty base runs |
LMR240-UF vs. RG-213
RG-213 is an excellent, proven heavy-duty coax and remains a good choice for longer permanent base-station installations. However, it is approximately 0.405 inch in diameter, compared with roughly 0.240 inch for LMR240-UF.
That makes LMR240-UF substantially smaller and easier to route through vehicles, radio cabinets, equipment racks and other confined spaces.
At CB frequencies around 27 MHz, RG-213 and LMR240-UF are both capable low-loss transmission lines. RG-213's larger conductor and heavier construction make it attractive for demanding fixed installations, while LMR240-UF offers an outstanding balance of low loss, small diameter and flexibility.
The Bottom Line
If you're currently using RG-58 or RG-8X, LMR240-UF is an excellent upgrade when you want to reduce coax loss without installing bulky 0.400-inch cable.
If you're considering RG-213, LMR240-UF gives you a much smaller, more flexible cable while retaining very good RF performance.
