PL259 UHF Cable 35ft KMR400 PL259 Male to Male Coaxial Cable - Low

In this review of the PL259 UHF Cable 35ft KMR400, the bottom line is simple: this cable is a solid, low loss option for radio operators who need a durable 35ft jumper with reliable performance. The reviewer found the cable best suited to CB, HAM and VHF setups where signal preservation over mid-range runs matters most, and the standout reason to buy is the low measured loss and sturdy connector construction that minimize degradation and failure in field use.

Key Features

• Low loss performance: The 35ft KMR400 construction delivers less than 1.11dB loss at 450MHz so signals remain strong across the length.
• Reliable SWR: Factory specs indicate an SWR near 1.25, which helps maintain efficient power transfer for radios and analyzers.
• Robust conductor build: A copper clad aluminium center and aluminum foil plus tinned copper braid outer shield provide good shielding and signal protection over distance.
• Connector durability: PL259 male connectors use a clamp design and a 2.2in heat shrink with adhesive to guard against separation and moisture ingress.
• Weather resistant jacket: PVC outer jacket and nickel-plated connector shells increase corrosion resistance and make the cable suitable for outdoor and marine VHF use.
• Wide compatibility: Works with CB, HF amateur, marine VHF, SWR meters, antenna analyzers and surge protectors using PL259 terminations.

Who It's For

The PL259 UHF Cable 35ft is aimed at hobbyist and semi-professional radio users who need a mid-length low loss coax for base antennas, mobile rigs temporarily installed, or test setups that require PL259 male to male connections. It is especially useful for operators monitoring 160-10M and VHF ranges who want to keep cable loss to a minimum without stepping up to much larger commercial feeds.

Those who should look elsewhere include users who need extreme flexibility or bend radius for tight routing, since multiple customers described the cable as relatively stiff. Also, if a user requires an exact copper solid center or a different connector type, this KMR400 with copper clad aluminium and PL259 ends may not match that requirement.

Pros & Cons

Pros

• Low measured signal loss at 450MHz, preserving signal strength on longer runs.
• Sturdy outer jacket and nickel-plated shells resist moisture and corrosion outdoors.
• Connector assembly with long adhesive-lined heat shrink reduces chances of separation or water ingress.
• Good value for hobbyists seeking LMR400-equivalent performance without premium pricing.

Cons

• Relatively stiff cable that can be harder to route in tight spaces or for flexible installations.
• Solder quality on some connectors drew mixed comments from users, though functional performance was generally reported as good.

Our Verdict

The PL259 UHF Cable 35ft KMR400 is a practical, value-oriented coax for CB and amateur radio operators who need low loss over a 35ft run and a durable PL259 connection. It balances solid shielding and weather resistance with well-integrated connectors, making it a sensible purchase for most base and marine VHF installations - just be aware of its reduced flexibility compared with thinner coax.

Frequently Asked Questions

Is this cable suitable for outdoor antenna runs?
Yes. The PVC jacket and nickel-plated connector shells provide moisture resistance appropriate for outdoor and marine VHF use.

Will I see noticeable signal loss with this 35ft cable?
No. The KMR400 construction yields less than 1.11dB loss at 450MHz, so signal degradation should be minimal for typical radio use.

Are the PL259 connectors reliable?
The connectors use a clamp design and long adhesive-lined heat shrink to reduce separation and water ingress; some users noted mixed solder quality but overall functional reliability was reported as good.
