The center conductor is copper-clad aluminum and so it is a bit lighter in mass than that with pure copper center conductors, and is still a substantial and low loss cable for use at HF frequencies. While the product photo shows a wooden spool, that is not included in the order. What one will get is a nicely wound length of coax for termination by the user. I used crimp-on fittings and am very pleased with this coax cable. No problems or issues at all - it is a drop-in replacement for LMR-400 and RG-8 coax. Recommended! Great value for its price. Review: Great value at lower price - The KMR400 coax has the same specifications as the Times Microwave standard LMR400 cable but at about 1/3 the price. This cable is constructed similarly to the LMR400 and is similarly a very stiff cable. The cable is not like the Times Microwave UltraFlex version which is much more flexible and has a slightly larger power loss. The connectors solder easily to the KMR cable, but the outer shield wire seems frizzier the LMR. I measured the coax cable loss with a MFJ 259 analyzer and verified the loss was the same as specified which is the same as the LMR. I use this cable for all feedlines outside my ham radio shack. Inside, I use the LMR400 UltraFlex cable. For portable antennas, shorter feedlines and lower frequencies I use the MOOKEERF coax found on desertcart. The MOOKEERF cable is smaller, has more loss and is cheaper. ## Features - 👍 【Ultra Low Loss】— This 50 feet kmr400 coax cord without connector is black in color and it is Ultra Low-Loss Coax Cable.

Used this exclusively for a new tower installation with four antennas. ## Frequently Bought Together - XRDS -RF KMR400 RF Coaxial Cable 50 Ohm Low Loss Coax Cable 50 Feet - MOOKEERF PL-259 Male Crimp Connector Adapter,UHF SO239 Crimp Coax Connector for LMR400/KMR400/RG8/RG8U/RG213 Coaxial Cable (Pack of 10) - Riotaxy Pack of 10 N Male Plug Crimp Connector 50 ohm for LMR400 Belden 9913 RG8 Nickel Machined Brass Construction (10 Piece N Male for lmr400) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/215237111-xrds-rf-kmr400-rf-coaxial-cable-50-ohm-low-loss](https://www.desertcart.pl/products/215237111-xrds-rf-kmr400-rf-coaxial-cable-50-ohm-low-loss) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
