N to SMA coax cable can also be used for connecting lightning arresters, meters, or signal boosters Thin, flexible, light-weight 240-sized coax makes installation easier, especially for tight bends. Specifications Connector 1: SMA Male plug 50 ohm Connector 2: N Male plug 50 ohm Length: 25 feet Coax: Low-loss LMR-240 size (0.240 inch diameter) Impedance: 50 ohm NOT for use with Wi-Fi (RP-SMA) or video (cable/satellite/CATV) devicesProxicast's coax extension cable assemblies are constructed with top quality extremely low-loss cable and gold plated connectors. Each cable assembly is fully tested. Proxicast recommends LMR195 coax for assemblies up to 10 ft, LMR240 for lengths up to 25ft and LMR400 for lengths up to 75 ft.RF ConnectorsSMA Female jacks are commonly used on 3G/4G/LTE cellular modems, routers and signal amplifiers - check with your equipment manufacturer. Many indoor cellular antennas have SMA Male connectors; most outdoor antennas have either N-Male or N-Female connectors.RP-SMA (Reverse Polarity) connectors are commonly used on Wi-Fi equipment. SMA and RP-SMA connectors will not mate.Video equipment (cable, satellite, TV, etc) uses "F" connectors - which look similar to SMA but they will not mate with SMA connectors.See the photo gallery above for pictures of the exact connectors on this coax extension cable and note the gender of the connectors you need to ensure male-to-female mating.All outdoor connections should be weather-proofed to minimize moisture in the cabling. Use our Self-Bonding silicone tape for fast and easy connection sealing. Review: Well made. Good for Nano VNA use. - Using this on my Nano VNA, and it works very well for critical antenna measurements. Can easily measure/tune down to 1.01 VSWR. Connectors seem good quality. The coax is a bit stiff, but good coax usually is. Review: Value! - As a hobbyist, I am always looking for the best bang for the buck. WIth cabling, we all learn the long and hard way that you get what you pay for. In this case, I am very happy to have 400 performance with a 240 cable. Its like consumer level hardline. Can't be beat for a pre-crimped solution. I'm lookig forward to my next project which will cause me to check the 50', but again, perfect! ## Features - SMA-MALE TO N-MALE Coax Jumper Cable - Connect Between SMA Devices and Female N Type Antennas - BEST COAXIAL CABLE for 4G & 5G Signals - VERY LOW-LOSS DOUBLE SHIELDED LMR240-size 50-Ohm Coax Meets or Exceeds Times Microwave LMR240 Specifications - LESS SIGNAL LOSS than RG8x and 3d-fb N to SMA Cables - PRO-GRADE QUALITY - Gold Plated Signal Pins - Heat Shrink on Both Ends - 100% FACTORY TESTED - Each Cable Assembly is Fully Tested - TOUGH PE JACKET Withstands Abrasions & Provides Excellent Outdoor Moisture Resistance - COMPATIBLE with all SMA & N-based Devices including Modems, Routers, Lightning Arresters and Antennas from Cisco, Cradlepoint, Digi, MoFi, Pepwave, Proxicast, Sierra Wireless and many others - *NOT* for use with Wi-Fi, Helium (RP-SMA) or Cable/Satellite/TV Equipment (F Connector) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00QZEQ5EA | | Brand | Proxicast | | Brand Name | Proxicast | | Cable Type | Coaxial | | Cable type | Coaxial | | Color | 25 ft - CFD240 | | Compatible Devices | Amplifier, Antenna, Booster, Modem, Router | | Compatible Phone Models | Potentially compatible with smartphones, specific models unknown | | Compatible devices | Amplifier, Antenna, Booster, Modem, Router | | Compatible phone models | Potentially compatible with smartphones, specific models unknown | | Connector Gender | Male-to-Male | | Connector Type | Sma Male to N Male | | Connector type | Sma Male to N Male | | Customer Package Type | Standard Packaging | | Customer Reviews | 4.5 out of 5 stars 442 Reviews | | Indoor Outdoor Usage | Indoor, Outdoor | | Item Length | 25 Feet | | Item Shape | Round | | Item Weight | 340 g | | Manufacturer | Proxicast | | Model | ANT-140-020-25 | | Model Name | ProxiCast Low-Loss Coax Extension Cable | | Number of Items | 1 | | Number of Pins | 4 | | Other Special Features of the Product | Low Loss | | Outer Material | polyethylene | | Part Number | ANT-140-020-25 | | Recommended Uses For Product | Connecting SMA devices to N-Female antennas in outdoor or indoor settings for wireless communication applications, such as 4G/LTE/5G cellular broadband, ADS-B, GPS, and RF radio | | Special features | Low Loss | | Specification Met | RoHS | | UPC | 617237750112 | | Unit Count | 1 Count | ## Product Details - **Brand:** Proxicast - **Connector type:** Sma Male to N Male - **Cable type:** Coaxial - **Compatible devices:** Amplifier, Antenna, Booster, Modem, Router - **Special features:** Low Loss ## Images ![Proxicast 25 ft Low-Loss Coax Extension Cable (50 Ohm) - SMA Male to N Male - for 3G/4G/LTE/Ham/ADS-B/GPS/RF Radio to Antenna or Surge Arrester Use (Not for TV or WiFi) - Image 1](https://m.media-amazon.com/images/I/81s8woMbEfL.jpg) ![Proxicast 25 ft Low-Loss Coax Extension Cable (50 Ohm) - SMA Male to N Male - for 3G/4G/LTE/Ham/ADS-B/GPS/RF Radio to Antenna or Surge Arrester Use (Not for TV or WiFi) - Image 2](https://m.media-amazon.com/images/I/71IyeONUZSL.jpg) ![Proxicast 25 ft Low-Loss Coax Extension Cable (50 Ohm) - SMA Male to N Male - for 3G/4G/LTE/Ham/ADS-B/GPS/RF Radio to Antenna or Surge Arrester Use (Not for TV or WiFi) - Image 3](https://m.media-amazon.com/images/I/81ywfWMYJtL.jpg) ![Proxicast 25 ft Low-Loss Coax Extension Cable (50 Ohm) - SMA Male to N Male - for 3G/4G/LTE/Ham/ADS-B/GPS/RF Radio to Antenna or Surge Arrester Use (Not for TV or WiFi) - Image 4](https://m.media-amazon.com/images/I/81JH68A9JxL.jpg) ![Proxicast 25 ft Low-Loss Coax Extension Cable (50 Ohm) - SMA Male to N Male - for 3G/4G/LTE/Ham/ADS-B/GPS/RF Radio to Antenna or Surge Arrester Use (Not for TV or WiFi) - Image 5](https://m.media-amazon.com/images/I/81Y-1g2-lFL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well made. Good for Nano VNA use. *by D***E on 30 June 2020* Using this on my Nano VNA, and it works very well for critical antenna measurements. Can easily measure/tune down to 1.01 VSWR. Connectors seem good quality. The coax is a bit stiff, but good coax usually is. ### ⭐⭐⭐⭐⭐ Value! *by P***E on 4 February 2025* As a hobbyist, I am always looking for the best bang for the buck. WIth cabling, we all learn the long and hard way that you get what you pay for. In this case, I am very happy to have 400 performance with a 240 cable. Its like consumer level hardline. Can't be beat for a pre-crimped solution. I'm lookig forward to my next project which will cause me to check the 50', but again, perfect! ### ⭐⭐⭐⭐⭐ Excellent Quality, get the shortest run you need, longer isn't better amplifier may be required. *by F***G on 16 October 2018* Extremely well made, somewhat rigid, good weather seal. I purchased two of these for my MOFI 4500 router/receiver and one had thinner wire coating than the other? Odd. BE AWARE, that if you are using this to bring a signal into your MOFI unit inside, 25 feet will possibly cause line attenuation which results in slower speeds and weak reception. In order to get the best performance out of these cables from antenna to MOFI, you will also need a signal booster/amplifier for each antenna which costs more than the antennas and cable combined. These do allow you to place antennas outside while having your router inside for easy access and signal enhancement. Get the shortest cables you need, longer cables require amplification for best performance. Very happy with the quality of these coax extension cables and I definitely recommend them. ## Frequently Bought Together - Proxicast 25 ft SMA Male to N Male Premium 240 Series Low-Loss Coax Cable (50 Ohm) for 4G LTE, 5G Modems/Routers, Ham, ADS-B, GPS to Antenna or Surge Arrester Use (Not for TV or WiFi) (ANT-140-020-25) - Proxicast Pro-Grade Extra Strong 30mil Weatherproof Self-Fusing Silicone Rubber Sealing Tape For Outdoor Antenna Coax & Electrical Cables, Hose/Pipe Leaks & Emergency Repairs (1.5" x 15' roll) - Black - Proxicast High Gain 10 dBi Universal Wide-Band 4G / LTE, 5G & WiFi Omni-Directional Outdoor Pole/Wall Mount Antenna for Verizon, AT&T, T-Mobile (ANT-126-002) --- ## 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.tn/products/263765142-proxicast-25-ft-low-loss-coax-extension-cable-50-ohm](https://www.desertcart.tn/products/263765142-proxicast-25-ft-low-loss-coax-extension-cable-50-ohm) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-25*
