It took me months to find this. And it’s perfect. Now I can watch the birds live again. :) Review: Works like a charm! - I bought this for my son who is college and an aavid gamer. He needs all the signal he can get! (This replaced a wired antena after his cat chewed through the wire). He (son, not the cat) happily reports zero issues with his internet connection. The only reason this didn't get a 5th star is that I needed to get him some adapters to make this work. Make certain that the receiving end is female (his was not). Even with that minor setback the price and performance make this a good deal! ## Features - Dual band wifi antenna: 2.4GHz (2400-2500MHZ ) / 5.8GHz (4900-5900MHz) - High gain: 12 dBi; WiFi connector: SMA male; Input impedance: 50Ω; Standing wave ratio: ≦ 1.5; SWR=1.5 (2.4GHz), SWR=1.4 (5.8GHz) - Compatible with: Wireless Network Router, WiFi AP Hotspot Modem, WiFi USB Adapter, Desktop PC Wireless Mini PCI Express PCIE Network Card Adapter - Application: WiFi IP Security Camera, Reverse Camera, Wireless Video Surveillance DVR Recorder, Backup Camera, network device, Industrial Router IoT Gateway Modem, Dual Frequency Devices and so on. - You will get: 2 x WiFi Antennas 12dBi with SMA male (Please ensure that the connector of your device is an external thread internal hole) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D5Y9DK5H | | Antenna | WiFi Antenna | | AntennaDescription | WiFi Antenna | | Best Sellers Rank | #191 in Computer Networking Antennas | | Brand | Stemedu | | Color | Black and red | | Customer Reviews | 4.4 out of 5 stars 37 Reviews | | Impedance | 50 ohm | | Item Dimensions L x W x H | 7"L x 1"W x 1"H | | Manufacturer | Stemedu | | Number of Channels | 2 | | Number of Items | 2 | | Product Dimensions | 7"L x 1"W x 1"H | | Unit Count | 2 Count | | Warranty Description | 1 | ## Product Details - **Antenna:** WiFi Antenna - **Brand:** Stemedu - **Color:** Black and red - **Impedance:** 50 ohm - **Manufacturer:** Stemedu - **Number of Channels:** 2 - **Number of Items:** 2 - **Product Dimensions:** 7"L x 1"W x 1"H - **Unit Count:** 2 Count ## Images ![2PCS 12dBi Dual Band WiFi Antenna 2.4GHz 5.8GHz SMA Male Wi-Fi Antennas High Gain Universal for Wireless Network Card Security IP Camera WiFi Router Hotspot Desktop PC Repeater - Image 1](https://m.media-amazon.com/images/I/51jfyDJU0IL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great antenna! *by S***F on May 4, 2026* Excellent replacement for HiBird bird feeder antennas!
