Highlights
- 【LOW LOSS 】- The loss of 25ft KMR400 pl259 coaxial cable at 450MHZ signal frequency is less than 0.85dB and the SWR ≤ 1.25. It is a low loss uhf coax cable with PL259 plugs on the both ends. There is no need to worry about signal loss for long-distance high-frequency use.
- 【Well Built Structure】- The inner conductor of this pl259 cable is made of copper clad aluminium, and the outer conductor is made of Aluminum foil and tinned copper braid which could maximum protect the signal over large distance. This KMR400 coaxial cable is equivalent to lmr400 and rg8u.
- 【Prevent Fall Apart or Break】- Connection between UHF male connector and KMR400 coaxial cable end is equipped with a 2.2" heat shrink tube with lined adhesive which is longer than other cable 's 1.1” heat shrink tube . And the connector is use clamp design.UHF connectors are well integrated into the cable to avoid easy breakage during use.
- 【Great Quality and Durable】 - The jacket of this cb cable is made of PVC,which is waterproof .The connector shell made of copper nickel plating has good corrosion resistance. The shrink tubing of this jumper is built with an adhesive inner wall, sealing against moisture. It is very sturdy that could work well in outdoor environment.
- 【Applications】This pl259 male to male coax cable could be used for CB ham radio, HF amateur radio, marine boat VHF radio, antenna, swr meter, surge protector, Walkie Talkies

Detailed Review
The MOOKEERF 25-foot KMR400 PL259 UHF Coaxial Cable connects radio equipment, meters, and antennas while minimizing signal degradation over distance. Fitted with UHF male (PL259) connectors on both ends, it serves operators setting up CB rigs, HF amateur stations, marine VHF radios, and walkie-talkie connections.
Signal integrity relies on an internal build featuring a copper-clad aluminum center conductor surrounded by dual shielding: aluminum foil and a tinned copper braid. Operating at 450MHz, this cable maintains a signal loss below 0.85dB with an SWR of 1.25 or lower. The KMR400 specification provides an equivalent alternative to standard LMR400 and RG8U coaxial lines.
Physical durability focuses on the connection points, which utilize a clamp design. Each end is protected by a 2.2-inch heat shrink tube lined with adhesive, sealing out moisture and preventing the connectors from pulling apart during handling. The outer waterproof PVC jacket and copper nickel-plated connector shells offer corrosion resistance for outdoor placement.
The main trade-off is the fixed 25-foot run, which may leave excess slack in compact stations or fall short in large tower setups. Additionally, the inner conductor is copper-clad aluminum rather than pure copper, which is standard for this cable type but worth noting for specific build preferences.
Verdict: The MOOKEERF KMR400 cable is a solid, durable choice for radio hobbyists and marine operators needing a ready-to-use 25-foot jumper with strong moisture protection and low signal loss.

Who Should Buy It
A great fit if you:
- Need a 25-foot low-loss feedline for a CB, ham, or marine VHF radio setup.
- Operate equipment outdoors and need adhesive-sealed, waterproof connections.
- Want an assembled jumper that connects directly to PL259 UHF female ports.
Consider something else if you:
- Require a cable length significantly shorter or longer than 25 feet.
- Need pure solid-copper inner conductors rather than copper-clad aluminum.
- Use equipment requiring BNC, SMA, or N-type connectors instead of UHF PL259.
