The cable works as designed, and while stiff, gets the job done. ### ⭐⭐⭐⭐⭐ Solid *by on Reviewed in the United States April 30, 2025* Large, thick, very well made cable. The quality is apparent. You will notice that it's fairly stiff from all the shielding. I have no connection or signal issues. Would recommend. ## Frequently Bought Together - XRDS -RF KMR400 SMA to N Cable 25ft, N-Male to SMA-Male Connector Low Loss Extension Cable 50 Ohm SMA Cable for 3G/4G/5G/LTE/ADS-B/Ham/GPS/WiFi/RF Radio to Antenna Use (Not for TV) - 5.5dBi 1090/978 N-Type Female Antenna - 26-inch - ADSBexchange.com Blue R820T2 RTL2832U, 0.5 PPM TCXO ADS-B SDR w/Amp and 1090 Mhz Filter, Antenna & Software on Industrial MicroSD --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/215237112-xrds-rf-kmr400-sma-to-n-cable-25ft-n-male](https://www.desertcart.tn/products/215237112-xrds-rf-kmr400-sma-to-n-cable-25ft-n-male) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-17*
