If you buy the 259's Don't come with the reducers so you'll have to search them too. **Q: what is power handling at ham hf freq?** A: I generally only use RG400 for building short jumpers, RF chokes and baluns. I've run 5KW through these with no problem, but I'm not certain about the exact specification. I started using this after disassembling a DXE 5KW balun and saw that it is what they used. **Q: What is the velocity factor of this coaxial cable?** A: I'm not certain for this manufacturer, but almost all RG400 is around 70% (±0.5%). I typically only use this for building indoor RF chokes, baluns and short jumpers. It will handle 5KW with no problem and is great for minimizing RFI. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good wire *by S***E on July 27, 2025* Good wire. ### ⭐⭐⭐⭐⭐ Duble sheled silver tined coper. *by R***. on June 10, 2025* Hi quality good stuff. ### ⭐⭐⭐⭐⭐ Very similar to Mil-spec cable *by E***E on May 2, 2023* Being unmarked and at a price of about 1/3 that of Mil-spec RG-400, I was skeptical but decided to give this a try for a non-critical application -- and I was pleasantly surprised. I measured the 40 foot length with a professional grade vector network analyzer (VNA) and compared it to a length of Mil-spec cable I'd previously purchased from a reliable source.Velocity factor and characteristic impedance (Z0) of the two cables were virtually identical. Also, the Z0 of this cable was at least as constant along the 40 foot length as that of the Mil-spec cable, indicating that the physical construction is uniform with no anomalies. The shields appear to be as tightly wound as those of the Mil-spec cable.The only difference I could detect was a slightly higher loss. I measured the loss only between 3 and 200 MHz which was the range where I'll be using it. The loss of this cable was about 6% greater at 3 MHz, and 1 to 2 percent greater at 10 - 200 MHz. These could indicate that the silver plating on this cable isn't as thick, or might be some other material. This small difference in loss itself would be insignificant in just about any application, but if due to a plating difference it might mean that the cable would deteriorate in a shorter period than the Mil-spec counterpart, if exposed to the environment for a long time.At least as far as I'm able to determine, this cable will be useful for a lot of applications calling for RG-400/U, at greatly reduced expense. ## Frequently Bought Together - Eightwood RG400 RF Coax Cable M17/128 Double Shield Coaxial Cable 40 feet - MOOKEERF 10 Pack 50 Ohm BNC Male Crimp Connector,BNC/Q9 Connector for RG58/RG142/RG400/LMR195/KSR195/3D-FB Cable - MOOKEERF TNC Male Connector 10PCS, TNC Male Plug Crimp Connector for RG58/RG142/RG400/LMR195/KSR195/3D-FB Cable --- ## 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.ph/products/184732169-rg400](https://www.desertcart.ph/products/184732169-rg400) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-04-25*
