Review: Ero scettico... - Quando mi hanno consigliato questo prodotto ero parecchio scettico in quanto da ignorante non sapevo cosa volesse dire 9dbi ma quando l'ho testata non ne faccio più a meno. Questa antenna permette (a campo libero e senza niente che ostacoli il segnale) di raggiungere segnali wifi ben più lontani di quelli dei vicini di casa. Testato in campagna dove c'è poco inquinamento del segnale ho raggiunto (con due tacche su 4) il wifi della cascina vicina( che è a circa 700m) ## 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 | #49,393 in Computers ( See Top 100 in Computers ) #120 in Network Antennas | | Brand | ALFA Network | | Color | black | | Colour | black | | Country of Origin | Taiwan | | Customer Reviews | 4.4 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 | | Maximum Range | 10 Meters | | Maximum range | 10 Meters | | Mfr Part Number | 4718050300167 | | Model Number | 4718050300167 | | Number of Channels | 1 | | Number of Items | 1 | | Number of Packs | 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 - **Impedance:** 50 Ohms - **Number of channels:** 1 ## Images ![Alfa Network Alfa Indoor 9dBi Omni Antenna Black ARS-N19 - Image 1](https://m.media-amazon.com/images/I/51H2XZeuOZL.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. ### ⭐⭐⭐⭐⭐ Ero scettico... *by A***I on 1 February 2018* Quando mi hanno consigliato questo prodotto ero parecchio scettico in quanto da ignorante non sapevo cosa volesse dire 9dbi ma quando l'ho testata non ne faccio più a meno.
