100 ft 50 ohm PL-259 Coaxial Cable

This 100 ft coaxial cable uses a KMR 400 type construction with PL-259 connectors on both ends. It is built for ham radio, CB radio, two-way radio and similar RF applications that require a 50 ohm impedance. The cable suits operators who need a long, low-loss feed line for base or mobile antenna installations. It is not for buyers who need a shorter run or a different connector type.

Low-Loss Limits at 50 ohm

The cable uses a copper-clad aluminium centre conductor measuring .41 inches in diameter, giving lower attenuation than RG58 or 240 type coax. The UV-resistant RF-PVC jacket is rated for 20-year outdoor exposure in harsh environments. Nickel-plated PL-259 clamp connectors with 2.2 in adhesive-lined heat shrink provide sealed, waterproof joints. The assembly is not suited for applications that demand a different impedance or connector standard.

Centre Conductor Diameter Decides Loss

The .41 inch copper-clad aluminium centre conductor is the single specification that determines whether this cable meets your link budget. A larger conductor reduces resistive loss compared with thinner RG58 or 240 cables, making it the decisive factor for long 100 ft runs at 50 ohm. If your system requires a smaller or larger conductor size, this KMR 400 assembly will not match the needed attenuation figure.

Questions about this item

Should I choose the 100 ft length or a shorter run for my ham radio antenna?

The 100 ft length suits distant antenna placements; every extra foot adds attenuation, so use the shortest run that reaches your mounting point.

What does the .41 inch center conductor mean for signal retention on my CB radio?

The larger .41 inch copper-clad aluminium conductor keeps loss lower than RG58 or 240 type coax, preserving more power at the antenna over 100 ft.

How does the PL-259 interface cap performance in practice?

The PL-259 UHF connectors handle 50 ohm systems up to VHF/UHF bands; nickel-plated clamp style resists pull-out and water ingress better than crimp versions.
