Cable type and purpose

This BFKK KMR 400 coaxial cable is a 12 ft low-loss 50 ohm transmission line terminated with PL-259 UHF male connectors. It is built for amateur radio, CB, VHF, HF and marine antenna installations where signal retention over distance matters.

Who should use it and who should not

It suits operators who need a durable, UV-resistant cable with clamp-style PL-259 connectors and adhesive-lined heat-shrink sealing for long-term outdoor exposure. It is not for installations that require a different characteristic impedance or a connector type other than PL-259 UHF male.

The specification that decides fit

The cable presents a 50 ohm characteristic impedance and uses PL-259 UHF male connectors on a 12 ft length; if your radio, antenna, meter or surge protector expects that impedance and connector combination, this assembly will connect directly.

Questions about this item

How can I confirm the KMR 400 cable is passing signal correctly after connecting it to my radio and antenna?

Measure SWR with a meter; a low, stable reading across your operating band shows the 50 ohm line and PL-259 connectors are working as intended.

What comes with the 12 ft cable and what must I supply separately?

The cable arrives with nickel-plated PL-259 UHF male connectors already crimped and sealed by 2.2 in adhesive-lined heat-shrink; you only need to provide the radio, antenna and any mounting hardware.

Why choose the KMR 400 version over the thinner 240 or RG58 types listed in the description?

The 0.41 in copper-clad aluminium centre conductor gives lower loss per foot, making the 400 series better for longer runs or higher frequencies than 240 or 58 type coax.
