PISKEKAT KMR400 PL259 Male to Male Coaxial RF Cable 100ft

SKU CH-2SY9-6GAZS

100 ft KMR400 coaxial cable with PL259 male connectors delivers under 2.8 dB loss at 450 MHz and 1.25 SWR for long-range RF links

  • TypeOther
  • Low loss — 2.8 dB at 450 MHz over 100 ft with 1.25 SWR
  • Robust shielding — aluminium foil plus tinned copper braid protects signal over distance
  • Copper-clad aluminium centre conductor resists oxidation for lasting performance
  • Weatherproof PVC jacket and nickel-plated PL259 connectors withstand outdoor use
  • 2 in adhesive heat-shrink at each end prevents connector pull-out

100ft KMR400 PL259 Coaxial Cable

This 100ft KMR400 coaxial cable uses PL259 male connectors on both ends for UHF radio installations. It suits CB, ham, marine VHF and antenna analyser setups that need a single long run. The KMR400 construction targets low attenuation at VHF and UHF frequencies. Installers who need a different connector type or a shorter length should choose another cable.

Signal Loss and Weather Resistance

At 450MHz the 100ft run shows under 2.8dB loss with a 1.25 SWR, preserving signal strength over distance. The copper-clad aluminium centre conductor pairs with aluminium foil and tinned copper braid for shielding. A PVC jacket resists water and UV for permanent outdoor routing. No power-handling or temperature ratings are supplied.

Reinforced Connector Strain Relief

Each PL259 plug includes a 2.2in adhesive-lined heat-shrink sleeve that bonds the connector to the cable jacket. This longer sleeve reduces pull-out risk when the cable is tensioned or vibrated. Nickel-plated connector bodies resist oxidation in salty or humid air. No tools, adapters or software are bundled with the cable.

Questions about this item

How do I install the PL259 connectors on this 100ft KMR400 cable without pulling them loose?

Route the cable, then push each PL259 firmly until the 2.2 inch adhesive-lined heat-shrink tube seats fully; the bond prevents the connector from pulling off during tension or vibration.

What part of this coaxial cable will need replacement first?

The PVC jacket resists water and UV, but prolonged outdoor exposure will eventually degrade it; inspect annually and replace the cable if the jacket cracks or the nickel-plated connector shells show corrosion.

At what signal loss does this 100ft run become the limiting factor?

At 450 MHz the cable attenuates less than 2.8 dB with a 1.25 SWR; beyond that frequency loss rises, so the 2.8 dB figure marks the practical limit for low-loss operation.
