Black coaxial cable 35 ft long with PL-259 connectors and heat-shrink seals

BFKK

BFKK KMR 400 PL-259 Coaxial RF Cable 35 ft

SKU CH-X8K3-87B3D

A 35 ft low-loss 50 ohm coaxial jumper with PL-259 connectors, swept to 1.35 VSWR and losing only 0.26 dB per 3 ft at 500 MHz

  • Overall length35 ft (10.7 m)

Length 35 ft.

  • Professionally manufactured with 20 years experience, VSWR below 1.35 verified
  • Ultra-low loss design, only .26 dB attenuation per 3 ft at 500 MHz
  • 60% less signal loss than RG-58 at Wi-Fi frequencies for marine use
  • Heavy-duty PL-259 clamp connectors prevent accidental disconnection during operation
  • 2 in adhesive-lined heat shrink provides sealed, weatherproof connector junctions

Professional CB & Ham Radio Cable

This 35 ft coaxial jumper is built for CB radio, HAM, VHF marine antenna, AIS, antenna analyser, dummy load and SWR meter installations. It uses KMR 400 cable with PL-259 UHF male connectors on both ends for a secure 50 ohm link in base-station or mobile setups.

Ultra-Low Loss KMR 400 Construction

The KMR 400 dielectric attenuates only 0.26 dB per 3 ft at 500 MHz, giving roughly 60 % less loss than RG-58 at Wi-Fi frequencies. Swept testing guarantees VSWR below 1.35, while high-density tinned copper braid provides 100 % shielding for clean reception and transmission.

Heavy-Duty Outdoor Build

Nickel-plated RF Industries connectors with heavy mount-clamp attachment resist pull-out better than crimp types. A 2.2 in adhesive-lined heat-shrink tube seals each joint against moisture. Copper-clad aluminium conductor and UV-proof RF-PVC jacket are rated for 20-year outdoor exposure in harsh environments.

Questions about this item

What does the 0.26 dB loss per 3 ft at 500 MHz mean for my radio link?

Over a 35 ft run the loss is about 3 dB at 500 MHz, roughly half the signal power, so keep the cable as short as practical for higher frequencies.

How does the KMR 400 cable type and PL-259 connector limit usable frequency?

KMR 400 is a low-loss 50 ohm coax; PL-259 UHF connectors are generally used up to 500 MHz, matching the tested 500 MHz figure.

What mounting clearance does the heavy PL-259 clamp connector and 2.2 in heat-shrink need?

Allow at least 2.2 inches behind the connector for the adhesive-lined heat shrink and the clamp body to seat without stress.
