Review: Poor WiFi signal strenth? Upgrade to this Antenna.! - Wow! 5* to Alfa on a decent omni directional 9db Antenna that actually works! I bought 4 different products, a directional ariel from Alfa of 6db, junk! A 16db omni aerial from China, junk! Also, a 25db high gain Yagi directional aerial. Not arrived yet from China. Don't waste your money in desperation, like me, trying to get a decent WiFi network connection. Just buy the Alfa 9dbi Antenna. This nearly doubled the amount of WiFi strength I was getting with the 2.4ghz Alfa aerial. If your a penetration tester or want to use it for wardriving, then this is the one for you. ## Features - Alfa network ARS-N19 2.4GHz 9dB antenna (plastic pack) - Alfa Network ARS-N19 2.4GHz 9dBi Antenna (Pack of Plastic Pack) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B009H028CM | | Antenna | An indoor omnidirectional antenna with 9dBi gain, designed for general antenna applications | | AntennaDescription | An indoor omnidirectional antenna with 9dBi gain, designed for general antenna applications | | Best Sellers Rank | 71,551 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 571 in USB Computer Network Adapters | | Brand | ALFA Network | | Brand Name | ALFA Network | | Colour | black | | Country of Origin | Taiwan | | Customer Reviews | 4.3 out of 5 stars 261 Reviews | | EU Spare Part Availability Duration | 2 Years | | Global Trade Identification Number | 04718050300167 | | Impedance | 50 Ohms | | Item Type Name | Alfa Network ARS-N19 2.4GHz 9dBi Antenna (Pack of Plastic Pack) | | Item Weight | 0.06 Kilograms | | Manufacturer | InpexOpcion | | Manufacturer Part Number | 4718050300167 | | Maximum Range | 10 Metres | | Maximum range | 10 Metres | | Model Number | 4718050300167 | | Number of Channels | 1 | | Number of Items | 1 | | Number of channels | 1 | | Unit Count | 1.0 count | ## Product Details - **Antenna:** An indoor omnidirectional antenna with 9dBi gain, designed for general antenna applications - **Brand:** ALFA Network - **Colour:** black - **EU Spare Part Availability Duration:** 2 Years - **Impedance:** 50 Ohms - **Manufacturer:** InpexOpcion - **Maximum range:** 10 Metres - **Number of Packs:** 1 - **Number of channels:** 1 - **Unit count:** 1.0 count ## Images ![ALFA Network 9dBi WiFi high-gain screw-On OMNI-Directional swivel antenna for all 802.11g Routers using an RPSMA connector,Black - Image 1](https://m.media-amazon.com/images/I/51H2XZeuOZL.jpg) ![ALFA Network 9dBi WiFi high-gain screw-On OMNI-Directional swivel antenna for all 802.11g Routers using an RPSMA connector,Black - Image 2](https://m.media-amazon.com/images/I/416Zf5JUFwL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good *by V***. on 23 August 2025* Swapping the tiny default antenna with this resulted in a major signal boost in my case. ### ⭐⭐⭐⭐⭐ Poor WiFi signal strenth?

If your a penetration tester or want to use it for wardriving, then this is the one for you. ### ⭐⭐⭐⭐ Improved reliability of signal, although not strength *by M***Y on 7 May 2023* I bought this because my solar inverter kept losing connectivity to my wifi, which meant I was losing data on how well my solar installation was performing. The original aerial for the inverter was only 4 inches long. This Alfa aerial is 12 inches long. I had hoped this aerial would provide stronger reception for the wifi, however there's no change in the signal strength. What it has helped with is reliability - the inverter has not lost connection to the wifi at all since this aerial was installed.
